Oklahoma quarterback Kyler Murray apologized Sunday for several homophobic tweets that he deleted hours after winning the Heisman Trophy.

Murray, 21, had used an anti-gay slur in a tweet to friends when he was a teenager.

"I apologize for the tweets that have come to light tonight from when I was 14 and 15," he said on Twitter. "I used a poor choice of word that doesn’t reflect who I am or what I believe. I did not intend to single out any individual or group."

Oklahoma University did not respond to a request for comment by USA Today, which first reported on the tweets.

The tweets were deleted from Murray’s account early Sunday.

The re-discovered tweets put Murray, 21, in the company of other athletes finding themselves in a negative light just as they achieve success.

Racist tweets from Buffalo Bills quarterback Josh Allen’s teenage years resurfaced ahead of last year's NFL Draft.

After helping the Villanova Wildcats win the 2018 national men's basketball championship, a tweet by Donte DiVincenzo that contained racist rap lyrics was also brought to light.

Tweets by Josh Hader of the Milwaukee Brewers featured racist, homophobic and misogynistic words. The tweets -- which Hader posted as a teen -- drew attention earlier this year as he became one of the top relievers in the majors.

While he is known for football, Oklahoma's Murray was selected by baseball's Oakland A’s with the ninth overall pick in the 2018 MLB draft. He plans to report to spring training next year after his college football career ends. He led the Sooners to a Big 12 championship this season.
