The Court of Arbitration for Sport has rejected U.S. gymnast Jordan Chiles' request to retain her bronze medal from the Paris Olympics despite new evidence, according to USA Gymnastics.

"The Court of Arbitration for Sport (CAS) informed USA Gymnastics on Monday that their rules prohibit the reconsideration of an arbitral award, even if compelling new evidence is submitted," the U.S. gymnastics governing body stated. "We are profoundly disheartened by this decision and will continue to explore all available options and appeal procedures, including a petition to the Swiss Federal Tribunal, to guarantee a fair scoring, ranking, and medal allocation for Jordan."

Chiles initially placed fifth in the individual floor exercise at last week's Paris Olympic Games, but her coaches successfully appealed the scoring of one of the elements in her routine, resulting in her being promoted to the bronze medal position .

The judges mistakenly penalized one of the elements in her performance and subsequently rectified their error by awarding her the appropriate 0.1 points on appeal. As a result, her score rose from 13.666 points to 13.766 points, propelling her past two Romanian gymnasts to secure third place.

The decision to grant Chiles the bronze medal was made after Romania's Ana Barbosu had already begun celebrating her place on the podium. She left the stage in tears, and her coaches immediately challenged the ruling, arguing that Chiles' coaches had exceeded the one-minute time limit for appealing to the judges by four seconds.

The International Gymnastics Federation declared Barbosu the bronze medalist after the Court of Arbitration for Sport rejected the appeal filed by Chiles' coach. The CAS determined that Chiles' score had been incorrectly increased after the allotted time for challenges had passed. As a result, the CAS restored the original, inaccurate score of 13.666.

Following the CAS decision, the International Olympic Committee announced that it will award the bronze medal to Ana Barbosu (Romania). The IOC is working with the Romanian Olympic Committee to plan a medal ceremony and with the United States Olympic & Paralympic Committee to retrieve the bronze medal.

"USA Gymnastics expressed deep disappointment with the Court of Arbitration for Sport's decision concerning women's floor exercise," the organization stated in a post on Instagram on Saturday following the initial verdict, adding, "Throughout the appeal process, Jordan has faced persistent, entirely unfounded and highly damaging criticism on social media."

USA Gymnastics stated on Sunday that they possess video evidence confirming the appeal submitted by Chiles' coaches was filed 47 seconds after the inaccurate score was displayed, comfortably within the one-minute time constraint.

The CAS on Monday rejected the evidence because their regulations did not permit them to consider it.

USA Gymnastics stated on Monday that they would persist in their advocacy for Chiles, who has already returned to the United States with her bronze medal. She indicated on social media over the weekend that she would be stepping back from posting due to the ongoing controversy.

Gymnasts Simone Biles and Suni Lee both expressed their support for Chiles on Instagram over the weekend.

"Sending you tons of love, Jordan," Biles wrote in her post. "Keep your head up, Olympic champ! We adore you!"
