Four seconds too late.

Jordan Chiles’ bronze medal in floor exercise is now in the hands of the International Olympic Committee after her coach missed a one-minute deadline to clarify their score by four seconds.

The Court of Arbitration for Sport (ICC) made the ruling on Saturday, lowering the American gymnast’s final score to 13.666 points, a tenth of a point less than the score that put her on the podium five days ago, just behind Rebeca Andrade of Brazil, who won gold, and her teammate Simone Biles, who took silver.

The International Gymnastics Federation on Saturday upheld the court’s decision, reinstating Chile’s original score, which dropped it to fifth place, and declaring Romania’s Ana Maria Bărbosu third, but said the re-awarding of medals was up to the IOC.

The IOC did not immediately respond to a request for comment.

The appeal, in which Chiles’ coach argued that the initial score did not accurately reflect the difficulty of her routine, came too late in view of the competition rules, the court said.

The ruling came in response to an appeal by the Romanian Gymnastics Federation and gymnasts Bărbosu and Sabrina Maneca-Voinea. The court stated that Chiles’ original score “should be restored.” With a score of 13.666, Chiles is behind Bărbosu and Maneca-Voinea.

In the appeal hearing, the Romanian federation demanded that all three athletes finish in third place and be awarded medals, the court’s press release said.

Chiles, 23, posted two Instagram stories after the verdict: one included four broken heart emojis and a second that read: “I am taking this time and withdrawing from social media for the sake of my mental health, thank you.”

The verdict added a dramatic touch to one of the most tense moments of the Paris Games.

After Chiles finished her routine, Bărbosu beamed and held up the Romanian flag to celebrate winning the bronze medal. She didn’t know that Chiles’ coach had made a request. Chiles’ new score then appeared on the scoreboard, putting the American in third place.

When Chiles saw the changed score, she began to scream with joy. She jumped into her coach’s arms, then ran away, holding her head in her hands, overwhelmed by her emotions. Jade Carey, Chiles’ teammate, who was sitting in the crowd, dropped her jaw.

Bărbosu dropped the flag in shock and left the hall crying. Had she won the bronze medal that day, it would have been Romania’s first Olympic medal in women’s gymnastics since 2012.

As Chiles stepped onto the podium, she celebrated the first individual Olympic medal of her career.

“This medal means everything to me,” said Chiles afterwards. “It’s indescribable. I’m so proud of myself.”

Before Chiles’ examination, Bărbosu and Maneca-Voinea were tied for third place with identical scores of 13.700. Bărbosu won a tiebreaker because her execution score, which is part of the total score, was higher than her teammate’s. The judges found Bărbosu’s routine cleaner than Maneca-Voinea’s.

USA Gymnastics and the U.S. Olympic and Paralympic Committee said in a statement they were “devastated” by the ruling and would continue to stand by Chiles.

“The investigation into the difficulty level of Jordan Chiles’ floor exercise routine was submitted in good faith and, in our opinion, was in line with FIG rules to ensure accurate scoring,” the statement said. “Throughout the appeal process, Jordan was subjected to constant, completely unfounded and extremely hurtful attacks on social media. No athlete should be subjected to such treatment.”
