Larry Treaster appeals the circuit court’s granting of Respondents’ Motion to Dismiss for lack of subject matter jurisdiction. For the reasons set forth herein, we reverse.
Statement of the Facts
Appellant, Larry Treaster (“Treaster”) was employed by MoKan Transit Concrete, Inc. (“MoKan”), as a concrete truck driver. On January 9, 2003, working at a job site pouring concrete, the motor that powered the concrete truck’s drum 1 stopped operating, which caused the drum to stop turning. The truck was taken back to the MoKan’s location and some three hours later, after the concrete had begun to harden, Treaster’s supervisor, Steve Betts (“Betts”), directed Treaster to climb up onto the broken truck to pour water, through a hose, into the drum. At the same time that Treaster was on top of the drum of the broken concrete truck, the broken truck’s hydraulic lines were connected to the hydraulic lines of another operable truck in what is called a “crossover procedure.” This “cross-over procedure” caused the broken truck’s drum to rotate suddenly. Treaster was thrown from the concrete truck to the ground below, causing injury.
*489 Treaster and his wife filed a personal injury action against Betts, Alan Jenson, and John and/or Jane Doe(s) (“Respondents”) in the Circuit Court of Buchanan County, Missouri, on January 3, 2008. The Petition alleged negligent acts by Respondents that caused or contributed to cause Treaster’s injuries. Respondents filed a Motion to Dismiss alleging that Treaster’s claims were pre-empted by the Missouri Workers’ Compensation Law, Section 287.120. 2 On May 7, 2008, the circuit court dismissed the Petition finding that it lacked subject matter jurisdiction over this cause of action. 3 Treaster now appeals. 4
Analysis
The circuit court granted Respondents’ Motion to Dismiss, relying on the case law in effect at the time of its ruling, on the grounds that it lacked subject matter jurisdiction over the cause because it fell under the exclusive purview of the Workers’ Compensation Law.

See e.g., State ex rel. Taylor v. Wallace,
The Missouri Supreme Court subsequently has made it clear that the Workers’ Compensation Law’s exclusivity defense is not a matter of subject matter jurisdiction but rather constitutes an affirmative defense.
See McCracken v. Wal-Mart Stores E., LP,
Missouri’s constitution is unequivocal in stating that circuit courts ‘have original jurisdiction over all cases and matters, civil and criminal.’ Mo. Const, art. V, sec 14 (emphasis added).... [T]o the extent that some cases have held that a *490 court has no jurisdiction to determine a matter over which it has subject matter and personal jurisdiction, those cases have confused the concept of a circuit court’s jurisdiction-a matter determined under Missouri’s constitution-with the separate issue of the circuit court’s statutory or common law authority to grant relief in a particular case.
McCracken,
As an affirmative defense, that the claim is one covered by the Workers’ Compensation Law “must be pleaded and proved as provided in Rules 55.08 and 55.27. It is not a defense that may be raised in a motion to dismiss.”
Id.
at 479. A pre-trial dismissal based on an affirmative defense must be granted under the standards of summary judgment.

Fortenberry v. Buck,
The difference is significant, given that a more exacting standard applies to motions filed under Rule 74.04. In order to grant summary judgment based on section 287.120, the court must find that there is no genuine dispute as to the existence of each of the facts necessary to support the defendant’s affirmative defense.

If Respondents meet this threshold, the burden will shift to Treaster. In order to avoid summary judgment, Treaster would need to show that there is a genuine issue of material fact as to whether Respondents’ conduct falls within an exception to co-employee immunity. For example, Treaster claimed below that Respondents’ conduct satisfies the “something more” exception to co-employee immunity.

See Fortenberry,
Because the case must be sent back to the trial court for further proceedings, Treaster’s Point Two on Appeal is moot and need not be addressed.
With respect to the appeal from Treaster’s second filed petition against Respondents, WD71857, Treaster has not briefed or argued that the trial court’s dismissal of that Petition was in error under the pending action and abatement by prior action doctrines. “[Allegations of error not briefed or not properly briefed shall not be considered in any civil appeal....” Rule 84.13(a). Moreover, “[a] question not presented in an appellant’s brief will be considered abandoned on appeal and no longer an issue in the case.”
Lucky v. Sears Roebuck & Co.,
Conclusion
Accordingly, we reverse and remand case number WD71654 with instructions to proceed consistent with the principles set forth in this opinion. Case number WD71857 is dismissed.
All concur.
Notes
. The "drum” of a concrete truck is the part of the truck which stores the concrete and rotates.
. All statutory citations are to RSMo 2000, as updated through the 2002 Cumulative Supplement, unless otherwise indicated.
. Respondents suggest that the circuit court did not dismiss the case because it lacked subject matter jurisdiction but argues the court recognized that Treaster's exclusive remedy was provided by the Workers’ Compensation Law. A plain reading of the Judgment makes clear the circuit court concluded it lacked subject matter jurisdiction over the case because it did not find "something more" than mere negligence, which would have taken it out of the Workers’ Compensation Act.
. The procedural history of this case is more extensive than what is recited above, but further detail is unnecessary for the resolution of the issue before us. Essentially, Treaster filed his first petition in this case on January 3, 2008. This first case is case #WD69794. Treaster appealed the circuit court’s grant of Respondents’ Motion to Dismiss in the first case, but this Court dismissed the appeal because the judgment was not final.
See Treaster v. Betts,
.Section 287.120.2 sets forth the exclusivity provision of the Workers’ Compensation Law and states: "The rights and remedies herein granted to an employee shall exclude all other rights and remedies of the employee, his wife, her husband, parents, personal representatives, dependents, heirs or next kin, at common law or otherwise, on account of such accidental injury or death, except such rights and remedies as are not provided for by this chapter.”
. "When the applicability of section 287.120 appears from the face of the petition, a defendant can also properly file a motion to dismiss for failure to state a claim upon which relief can be granted,
see
Rule 55.27(a)(6), or for judgment on the pleading pursuant to Rule 55.27(b) if the affirmative defense appears from the petition and other pleadings.”
Fortenberry v. Buck,
. Fortenberry makes it clear that McCracken applies to cases pending on appeal at the time it was decided. Both parties agree that these holdings require this matter to be reversed and remanded to the trial court. Treaster asks this court to evaluate Respondents’ Motion to Dismiss as one for Summary Judgment and render a ruling as the Missouri Supreme Court did in McCracken. In the case at bar, unlike McCracken, essential facts are contested. Therefore, such an undertaking by this Court would be improper.
