OPINION
I. Introduction
In this accelerated, interlocutory appeal, Appellant Jason Maris, P.A.-C appeals the trial court’s order denying his motion to dismiss the health care liability claims of Appellees Tadd Hendricks, as independent executor of the estate of Melissa Hendricks, deceased, and Tadd Hendricks, individually and as next friend of Joshua and Daniel Hendricks, minors, and Charlie Morello. See Tex. Civ. PRAc. & Rem.Code Ann. § 51.014(9) (Vеrnon Supp.2007). In a single issue, Maris argues that the trial court erred by not dismissing Appellees’ claims because Appellees failed to serve him with an expert report complying with the requirements of section 74.351 of the civil practice and remedies code. See id. § 74.351(a), (b), (r)(6) (Vernon Supp.2007). We will affirm.
II. Factual and Procedural Background
Appellees filed their original petition on October 12, 2004, alleging a health care liability claim against Maris, a physician’s assistant who worked for Highland Family Medical Center. 1 Appellees averred that Maris had removed a lesion from Melissa Hendricks’s scalp in October 2002 but failed to send it off for appropriate pathological analysis, “thereby eliminating any opportunity for [Melissa] to be properly diagnosed and treated for a malignant condition.” Melissa sought treatment for a similar mass that developed on her scalp about a year later, which was removed by a different physician, sent to a pathology lab, and determined to be “malignant and significantly progressed.” Melissa subsequently underwent “extensive radical treatment,” but she died in December 2004.
The parties filed multiple expert reports and motions to dismiss. Appellees first attached the expert report of Rhett K. Fredric, M.D. to their original petition. The report did not mention Maris by name, but it set forth in part a chronology of events as evidenced by Melissa’s medical records, the standard of care applicable to the procedure, how the standard of care had been breached, and a statement of causation.
On November 21, 2005, Maris filed his first motion to dismiss challenging the adequаcy of Dr. Fredric’s expert report. See id. § 74.351(Z). Maris contended that the report did not name him and that Dr. Fredric testified in his deposition on November 15, 2005, “that he is not qualified to offer any opinions about physician assistants as he never worked with one and does not know the law.” On January 13, 2006, Maris filed a supplemental motion to dismiss with attached excerpts of Dr. Fredric’s deposition. Appellees respоnded that Maris had waived any objections to Dr. Fredric’s report for failing to object “not later than the 21st day after the date *382 it was served” and, alternatively, requested a thirty-day extension pursuant to section 74.351(c) to cure any deficiency. See id. § 74.351(c).
The trial court conducted a hearing on Maris’s first motion to dismiss on January 18, 2006, and found that Dr. Fredric’s report was “insufficient as to” Maris but granted Appellees a thirty-day extension to cure the deficiency. On February 16, 2006, Appellees filed another expert report signed by Dr. Fredric that named Maris. Maris conceded during argument in an August 13, 2007 hearing that “Dr. Fredric’s affidavit was corrected and fixed by then naming my client as — by name.... He was named in that correcting affidavit. ...”
Included with Appellees’ second supplemental response to a request for disclosure and designаtion of experts, which was filed on January 17, 2006, was an expert report from Sunti Srivathanakul, M.D. Dr. Sriva-thanakul reached the same conclusions as Dr. Fredric regarding the applicable standard of care, the manner in which the care provided by Maris failed to meet that standard, and the causal relationship between that failure and Melissa’s death. However, Dr. Srivathanakul “imploded” during his deposition on October 30, 2006, resulting in Appellees’ de-designating him as a testifying expert shortly thereafter.
At some point between December 1, 2006 and August 13, 2007, the trial court “ruled that Dr. Fredric could not testify against Maris due to his lack of qualifications.”

Thereafter, on March 23, 2007, the trial court signed an order granting Appellees’ motion for leave to designate new experts. Appellees filed the expert reports of Terrence Lee Moore, M.D. and Dennis Delasi, P.A. On May 29, 2007, Maris filed his second section 74.351 motion to dismiss, arguing in part that the new expert reports of Dr. Moore and physician’s assistant Delasi were untimely and should be dismissed because they were filed after the expiration of the section 74.351(a) 120-day deadline, which section 74.351(a) prohibits.
See id.
§ 74.351(a);
see also Danos v. Rittger,
On August 13, 2007, at the hearing on Maris’s second motion to dismiss, Maris argued thаt Appellees’ claims against him should be dismissed because (1) “now that Dr. Fredric has been stricken from this matter, his report obviously does not meet the standard under 74.351,” (2) Appellees de-designated Dr. Srivathanakul as an expert witness, “[s]o therefore, the standard-of-care requirements as an opinion regarding [Maris] have not been met timely by the plaintiffs,” and (3) the new expert reports were untimely under Danos 3 The trial court denied Maris’s motion to dismiss. It is from this interlocutory order that Maris appeals.
III. Section 74.351 Expert Reports
Like his arguments at the August 13, 2007 hearing, Maris contends that the trial court erred by not granting his motion to dismiss because (1) “Appellees served only one report inside the 120-day deadline that failed to mention Maris and that was from an expert who was unqualified to testify about the standard of care for a *383 physician’s assistant,” (2) Appellees “filed a second report outside the [120-day] deadline by an expert who also was unqualified to offer the opinions regarding the standard of care applicable to” Maris, and (3) “Appellees’ attempt to escape dismissal by serving the reports of two new experts more than two years past the deadline is not authorized....” Maris thus argues that Appellees failed to serve an expert report because the only reports served were not “expert reports” as defined by section 74.351(r)(6). Appellees respond in part that Maris waived any objections to the sufficiency of the report by fading to timely assert an objection. We agree with Appellees.
A. Standard of Review
We review a trial court’s ruling on a motion to dismiss under section 74.351 for an abuse of discretion.
Am. Transitional Care Ctrs. of Tex., Inc. v. Palacios,
B. Section 74.351 Requirements and Standards 4
Civil practice and remedies code section 74.351 provides that, within 120 days of filing suit, a plaintiff must serve expert reports for each physician or health care provider against whom a liability claim is asserted. Tex. Civ. Peac. & Rem.Code Ann. § 74.351(a). An “expert report” is a written report by an expert that provides a fair summary of the expert’s opinions regarding the “applicable standards of care, the manner in which the care rendered by the physician or health care provider failed to meet the standards, and the causal relationship between that failure and the injury, harm, or damages claimed.” Id. § 74.351(r)(6). “Each defendant physician or health care provider whose conduct is implicated in a report must file and serve any objection to the sufficiency of the report not later than the 21st day after the date it was served, failing which all objections are waived.” Id. § 74.351(a) (emphasis added). “If an expert report has not been served within [120 days] because elements of the report are found deficient, the court may grant one 30-day extension to the claimant in order to сure the deficiency.” Id. § 74.351(c) (emphasis added). If, on the other hand, a plaintiff does not serve a timely expert report, the trial court, on the motion of the affected physician or health care provider, shall, subject to section 74.351(c), enter an order dismissing the case with prejudice. Id. § 74.351(b).
As stressed by the italicized portions of the statute above, there is a dis
*384
tinction between an absent rеport and a report that is timely but deficient, which consequently affects the applicability of the twenty-one day waiver provision in section 74.351(a).
See Ogletree v. Matthews,
No. 06-0502,
Conversely, if a report has been timely served but does not meet the statutory definition of an “expert report” because the report has one or more deficiencies in its contents, the trial court may grant one thirty-day extension to cure the deficiencies; thus, unlike section 74.351(b), dismissal following a defendant’s motion complaining of a deficient, but timely, report is not mandatory.

C. Any Objections to Report’s Sufficiency Waived
Here, Appellees served Dr. Fredric’s report on Maris when they filed and served their original petition on October 12, 2004. Because Appellees served Maris with an expert report within 120 days of filing suit, the report was not an absent report necessitating the mandatory dismissal of Appellees’ claims. See Tex. Civ. Prao. & Rem.Code Ann. § 74.351(b). Maris’s argument that the repоrt is no expert report because it did not specifically name him is an objection and argument directed *385 to the report’s sufficiency. The question then is whether Dr. Fredric’s alleged deficient report implicated Maris, triggering the twenty-one day sufficiency objection deadline of section 74.851(a). See id. § 74.351(a).
The report sets forth a chronology of events as evidenced by Melissa’s medical reсords. It stated in part,
There are two different hands describing this visit and the subsequent surgery on October 21, performed at Highland Family Medical Clinic at which time a 1 cm mass lesion was removed from Ms. Hendricks’ scalp. There is no indication in the records that the material removed from her scalp was ever sent for appropriate pathological analysis.
Dr. Fredric opined that the “standard of сare in this case requires submission of all tissue removed from patients who present with a soft tissue mass for appropriate pathological analysis.” He also opined that the applicable standard of medical care had been breached for “[flailing to submit the tissue removed from Ms. Hendricks for appropriate pathological analysis” and for “[flailing to diagnose аnd treat the malignancy present in Ms. Hen-drickses] body.” Dr. Fredric further reasoned that “Highland Family Medical Clinic, by and through the acts and omissions of its staff, failed to meet the applicable standard of medical care or breached the acceptable standard of medical care.” He concluded that the “failure to conform to acceptable standards of medicаl care proximately caused the subsequent disability experienced by Ms. Hendricks, and ultimately will be a proximate cause of her death from metastatic soft tissue sarcoma.” Maris is the individual who removed the initial cyst from Melissa’s scalp.
We determine that Dr. Fredric’s report sufficiently implicated Maris’s conduct.
See Palacios,
*386 In light of Maris’s waiver of his sufficiency objections, the trial court’s subsequent determination thаt Dr. Fredric’s report was “insufficient as to” Maris and its grant to Appellees of a thirty-day extension to cure the alleged deficiency was superfluous and procedurally inconsequential, which Appellees had argued to the trial court. Moreover, the filing of Dr. Srivathanakul’s report after the expiration of the 120-day deadline likewise was of no effect because Appellees timely served Dr. Fredric’s report implicating Maris and Maris waived his sufficiency objections to the report. Maris’s arguments relying on Danos, which the supreme court has reversed, and complaining of the untimely filed new expert reports of Dr. Moore and physician’s assistant Delasi are inapposite for the same reasons.
Maris further contends that Ap-pellees failed to serve a timely report complying with the requirements of section 74.351(r)(6) because, having determined that Dr. Fredric “could not testify against Maris due to his lack of qualifications,” the trial court subsequently struck Dr. Fredric from testifying as an expert on behalf of Appellees.

Maris confuses a Daubert
7
motion challenging a testifying expert with a section 74.351-based motion to dismiss a health care liability claim. Nothing in section 74.351 provides that an expert report meeting the statute’s requirements is invalidated if the expert who signed off on the report is subsequently struck pursuant to a
Daubert
challenge, nor has Maris directed us to any such authority. Moreover, the supreme court has stated that the trial court’s inquiry when determining whether the report represents a good faith effort to comply with the definition of an expert report in section 74.351(r)(6) is limited to the four corners оf the report.
Palacios,
*387 We hold that the trial court did not abuse its discretion by denying Maris’s motion to dismiss Appellees’ health care liability claims. Accordingly, we overrule Maris’s sole issue.
IV. Conclusion
Having overruled Maris’s sole issue, we affirm the trial court’s interlocutory order denying Maris’s motion to dismiss Appel-lees’ health care liability claims.
Notes
. Appellees also asserted claims against Stephen A. Glaser, D.O. and Highland Family Medical Center, who are not part of this appeal.
. The record does not contain an order striking Dr. Fredric as an expert witness. Maris did, however, file a motion to strike Dr. Fredric on December 1, 2006, and Maris's counsel stated at an August 13, 2007 hearing that the trial court had struck Dr. Fredric as an expert, prohibiting him from "testifying as to standard of care or breach of duly of care as to [Maris].”

See Danos,
. The legislature amended section 74.351 in 2005, and the 2005 changes apply as follows:
only to a cause of action that accrues on or after the effective date of this Act [September 1, 2005], An action that accrued before the effective date of this Act is governed by the law applicable to the action immediately before the effective date of this Act, and that law is continued in effect for that purpose.
See Act of May 18, 2005, 79th Leg., R.S., ch. 635, § 2, 2005 Tex. Gen. Laws 1590, 1590 (codified at Tex Civ. Prac. & Rem.Code Ann. § 74.351 (Vernon 2005)). Because Appellees’ cause of action accrued before the effective date of the current version of section 74.351, the former version of section 74.351 that was effective for claims filed on or after September 1, 2003 applies, and all references to section 74.351 herein are to that version of section 74.351. See Act of June 2, 2003, 78th Leg., R.S., ch. 204, § 10.01, 2003 Tex. Gen. Laws 847, 875 (amended 2005) (current version at Tex. Civ. Prac. & Rem.Code Ann. § 74.351 (Vernon Supp.2007)).
. The cases that Maris relies оn to support his argument that Dr. Fredric’s report was no expert report are all distinguishable or inap-posite, partly because each of the defendants in those cases filed timely objections to the reports, unlike Maris.
See Davis v. Webb,
. Maris argued at the August 13, 2007 hearing on his motion to dismiss that “now that Dr. Fred[ ]ric has been stricken from this matter, his report obviously does not meet the standard under 74.351.” And Maris argues, "Because the trial court struck Dr. Fredric’s report as to Maris[,] ... Appellees never served an ‘expert report’ as defined by the statute.”
