Noah Lyles is bidding farewell to the 2024 Olympics.

The  COVID Team USA track star shared the update shortly after taking home the bronze medal in the men's 200-meter final with a positive COVID-19 diagnosis.

"I want to thank everyone for the supportive messages," Noah shared on Instagram Aug. 8. "I believe this will be the end of my 2024 Olympics. It is not the Olympic I dreamed of but it has left me with so much Joy in my heart."

Noah also sent congratulations to fellow Olympians Letsile Tebogo of Botswana and Team USA's Kenny Bednarek who picked up the gold and silver medals during the race, respectively. And while he is disappointed in having to bow out of the games, he's still thankful to everyone who tuned in to watch him.

"I hope everyone enjoyed the show," he continued. "Whether you were rooting for me or against me, you have to admit you watched, didn't you?"

The 27-year-old—who previously won gold in the men's 100-meter race—had a dramatic finish in the 200-meter final as he dropped to the track and appeared to be gasping for air before exiting the race in a wheelchair.

Following the intense moment, his mother Keisha Cane Bishop explained that the issues stemmed from Noah's COVID-19 diagnosis, which Noah also confirmed.

"I woke up early, about 5 a.m. on Tuesday morning," Noah told NBC Sports, "and I was just feeling really horrible and I knew it was more than just being sore from the 100. Woke up the doctors and we tested, and unfortunately it came up that it was positive for COVID."

Noah shared that he tried not to panic and reminded himself that he'd run in worse conditions.

"We just took it day by day," he said, "trying to hydrate, quarantined off, and I can definitely say it's taken its toll for sure. But I've never been more proud of myself for being able to come out here."

Noah was set to compete Aug. 9 as part of the men's 4x100-meter relay, but shortly after his 200-meter race, he wasn't doubtful he would be up for it, saying it might be best to leave the relay in the hands of Christian Coleman, Courtney Lindsey, Kyree King and Fred Kerley.

"I'm feeling more on the side of letting Team USA do their thing," he said. "They've proven with great certainty that they can handle it without me. And if that's the case, coming off today, I'm perfectly fine saying, 'Hey, you guys have more than enough speed to be able to get the gold medal.'"
