Linda Gay Allard confessed to her crime shortly after she was informed that she had failed a polygraph test. At trial, however, she contended the confession was coerced by the government agent. To counter this contention, the government was allowed to introduce testimony relat *531 ing to the conduct of the polygraph examination. On appeal Allard challenges her conviction, arguing that the district court erred in admitting this testimony and in giving a modified Allen 1 charge to relieve initial jury deadlock. Because we find the district court did not err as to either, we AFFIRM Allard’s conviction.
I
Linda Gay Allard contacted her local Wal-Mart store in 2003, complaining that her husband found straight pins in Hill-shire Farms summer sausage she had purchased from the store. In addition to contacting Wal-Mart, Allard filed a complaint with the U.S.D.A.’s Food Safety Inspection Service. The U.S.D.A. joined with the United States Secret Service and conducted an investigation of Allard’s claim. As a part of the investigation, Secret Service Agent William Wind conducted a polygraph examination with respect to both Allard and her husband. At the conclusion of Allard’s polygraph exam, Agent Wind informed Allard that the results indicated she had not been truthful. Allard then gave the following written confession: “I put the pins in the sausage before I left for work on Thursday, December 4, at 3 p.m. I was hoping to get money from Hillshire Farms. I got the pins from the sewing box.” Allard told Agent Wind that she and her husband had nearly $60,000 in consumer debt that they were struggling to repay.
Following her confession, the government charged Allard with one count of making a false claim of consumer product tampering in violation of 18 U.S.C. § 1365(c)(1). 2 At a pre-trial bench conference, the district court granted the government’s unopposed motion in limine to prohibit the introduction of evidence regarding the fact that Allard “was asked to take and did take a polygraph test or any of the results.” After a jury trial, Allard was convicted and sentenced to 366 days of imprisonment and three years of supervised release. Allard filed this timely appeal.
II
On appeal Allard raises two challenges to her conviction: First, she contends that the district court admitted testimony relating to her polygraph examination in violation of Federal Rules of Evidence 702 and 403; and second, she contends that the district court erred in giving the jury a modified Allen charge. We consider each of Allard’s challenges in turn.
A
The testimony relating to Allard’s polygraph examination was admitted during both the Government’s cross-examination of Allard, and Agent Wind’s testimony during the Government’s rebuttal.
Allard testified on direct examination that her confession was involuntary because it was coerced by Agent Wind. She stated that Agent Wind told her she could not leave until she wrote what he told her to write in her statement; that Agent Wind threatened her by stating that he could take her farm and arrest her at work; that Agent Wind refused to honor *532 her request for an attorney; that Agent Wind pushed her, shoved her, and told her to sit down and shut up; and that Agent Wind said he could make her children disappear.
Before cross-examining Allard, the government, reversing its earlier position, moved to introduce evidence regarding the polygraph test. The government argued that Allard’s “extraordinary allegations” made the polygraph “extremely relevant to the interview” and that evidence regarding the polygraph would “go a long way toward explaining the Government’s and Mr. Wind’s role in the interrogation.” The district court questioned the relevancy of the test because the issue regarding the confession was credibility and the polygraph was simply a “kind of recordation ... of ... pressures and indicators.” The government responded that the test was relevant to the progression of events preceding the confession and to the fact that her failure of the polygraph test lent credence to Agent Wind’s testimony that he judged her to be deceptive.
Allard objected to the admission of evidence relative to the test, arguing, inter alia, that the government had notice that she would testify that her confession was involuntary. The government responded that it did not know until Allard testified that her assertion of an involuntary confession would include allegations that a federal agent had physically threatened her.
After a recess, the district court read a proposed jury instruction to the parties, which instructed the jury that it could consider statements made by Allard and Agent Wind surrounding the polygraph test to determine those witnesses’ credibility, but that the result of the polygraph test was not admissible. Allard argued that the relevance of the test was outweighed by the prejudice to her from its admission because the jury would infer that she had failed the test and further, that evidence regarding the test should not be admitted because there was no evidence that polygraph test results are reliable. The government cited an opinion from another circuit,
United States v. Johnson,
1
Allard first contends that the district court’s admission of the rebuttal testimony violated Rule 702 because the Government failed to satisfy Rule 702 with respect to relevancy and reliability, and with respect to admissibility under
Daubert v. Merrell Dow Pharmaceuticals, Inc.,
The government argues that Allard did not challenge the admission of the poly *533 graph evidence at trial under Rule 702. Allard’s counsel, however, did object to the proposed jury instruction on the ground, inter alia, that there was “no consensus that polygraph evidence [was] reliable.” Thus, the district court was aware that Allard objected to the introduction of scientific evidence in connection with the polygraph test.
The requirements of Rule 702 and its progeny apply only to testimony offered by one tendered as an expert.
See
Fed.R.Evid. 702. The government did not proffer Agent Wind as an expert. Neither did Agent Wind claim to offer, or actually provide, technical, scientific, or expert testimony. Instead, Agent Wind was called in rebuttal to provide his account of the facts and circumstances surrounding Al-lard’s confession, in an attempt to counter Allard’s allegations that her confession was coerced. Accordingly, there was no evi-dentiary error under Rule 702. Although Agent Wind gave detailed testimony regarding how a polygraph test is administered and the different kind of responses the test measures, Allard never renewed an objection and did not challenge the fact that Agent Wind had not been qualified as an expert. To the extent that she challenges this testimony, we find no plain error.
See United States v. Miranda,
The district court instructed the jury that the results of the polygraph test were not admissible and that the admission of statements made by Allard and the person giving the polygraph test were being admitted for the “sole purpose” of assisting the jury in determining whether Allard’s confession was voluntary.

The district
*534
court clarified that there would be no evidence presented with respect to the outcome of the test, and stated: “There is no scientific evidence being admitted here.” Because the district court instructed the jury that it should consider any polygraph evidence only to determine the credibility of the witnesses and not as scientific evidence, and because we must presume that the jurors followed those instructions,
see United States v. Wyly,

Allard also argues, with respect to both rebuttal and cross-examination, that the district court admitted evidence relating to the polygraph examination in violation of Rule 403, that is, the probative value of the evidence is “substantially outweighed by the danger of unfair prejudice.” Fed. R.Evid. 403. The district court has broad discretion to weigh the relevance, probative value, and prejudice of the evidence in determining its admissibility under Rule 403.
United States v. Wilson,
This Circuit has not addressed the admissibility under Rule 403 of testimony relating to a defendant’s polygraph examination. However, we are persuaded by the holdings of other Circuits, finding that testimony concerning a polygraph examination is admissible where it is not offered to prove the truth of the polygraph result, but instead is offered for a limited purpose such as rebutting a defendant’s assertion that his confession was coerced.
See United States v. Kampiles,
In
Tyler v. United States,
the defendant testified that his confession was coerced. When the government rebutted this claim with the testimony of the polygraph examiner, the defendant moved to strike the examiner’s testimony that the defendant was told that the results indicated that the defendant was lying.
As we have said before, “it is well settled that the purpose of rebuttal testimony is to explain, repel, counteract, or disprove the evidence of the Adverse party .... [I]f the defendant opens the door to the line of testimony, he cannot successfully object to the prosecution accepting the challenge and attempting to rebut the proposition asserted.”
United States v. Delk,
B
Allard also argues that the modified
Allen
charge given by the district court was error as it had an inappropriate coercive effect on the jury. Allard did not object to the
Allen
charge at trial. In fact, she agreed that giving the charge “soundfed] reasonable”. Consequently, this Court’s review is for plain error.
See United States v. McClatchy,
The term
“Allen
charge” describes supplemental instructions to deadlocked juries “urging them to forgo differences and reach a unanimous verdict.”
United States v. Heath,
Ill
For the reasons stated above, we find that the district court did not err in admitting testimony relating to Allard’s polygraph examination, nor in giving the modified Allen charge to relieve the jury’s deadlock. Consequently, the judgment of the district court is
AFFIRMED.
Notes
.
Allen v. United States,
. 18 U.S.C. § 1365(c)(1) states:
Whoever knowingly communicates false information that a consumer product has been tainted, if such product or the results of such communication affect interstate or foreign commerce, and if such tainting, had it occurred, would create a risk of death or bodily injury to another person, shall be fined under this title or imprisoned not more than five years, or both.
. Just before the Government's cross examination of Allard the district court gave an instruction to the jury, which in relevant part provided:
In this case, the defendant challenges the truthfulness or the voluntariness of her statement, the statement that was admitted into evidence.
She does not dispute that the statement is her statement. She disputes the circumstances that gave rise to the statement. She challenges, as I said, the voluntariness of her statement. In this case, the rules of evidence permit then the admissibility of testimony that surrounds the giving of the statement.
A polygraph examination was administered to the defendant. The results of that examination are not admissible. However, the statements between the defendant and the person administering the polygraph examination are admissible for the purpose for — for the sole purpose, I should say, of you determining the defendant’s state of mind at the time of the giving of the statement and whether or not that confession or statement was voluntary or not.
It also gives you an opportunity or it is your province to determine the credibility of the witnesses who testify about the circumstances surrounding the giving of a
statement. So the circumstances and the statements made at the time are not admitted for the truth of the statements made then.
Repeat that. I'm admitting the statements and permitting you to hear questions and answers about things that were said months ago, not for you to decide whether they were being truthful then, but whether or not the witnesses are being truthful now about what occurred then. That's a little bit of a twist. So think about it a little bit.
So, you, the jury, will have the opportunity to determine the credibility of the defendant and Special Agent Wind’s testimony at this trial. It doesn't matter whether it was truthful then. It doesn't matter if they were telling truths or lies. The question is what are they saying now that might contradict or be in conflict with what was said then and can you believe one or both or any of what they have to say now about those events that occurred then. That's why it’s being admitted.
Therefore, do not speculate about any matter or matters that are not presented. For example, there will be no evidence presented as it relates to what the outcome of that examination was. You will not get any documents, you will not get any testimony, about the outcome of that examination. *534 You certainly might get testimony about what people said to each other about that examination. That’s different. There is no scientific evidence being admitted here. So keep that in mind. So you’re not to speculate about any matter or matters that are not presented, such as the test results. Your job is determining whether the witnesses involved are being truthful today about past events. That's what your job is.
. We note that the Ninth Circuit in
United States v. Miller,
