Heisman Trophy winner Kyler Murray had a Saturday to remember. But the Oklahoma quarterback's memorable night also helped resurface social media's memory of several homophobic tweets more than six years old.

When Murray was 15 years old, he tweeted at his friends (via his since-verified Twitter account) using an anti-gay slur to defame them. Four offensive tweets remained active on his account late Saturday night but were eventually deleted by Sunday morning — when Murray apologized for his insensitive language in a tweet.

Murray took accountability Sunday morning and said the "poor choice of word" doesn't "reflect who I am or what I believe. I did not intend to single out any individual or group."

Murray, 21 now, joins several other famous athletes to find themselves thrust in a negative spotlight as a result of their old tweets resurfacing in the midst of big accomplishments. The Milwaukee Brewers' Josh Hader had racist, homophobic and misogynistic tweets resurface from when he was 17 years old this past summer. Buffalo Bills quarterback Josh Allen saw racist tweets resurface from his teenage years ahead of the NFL draft. And Villanova Final Four Most Outstanding Player Donte DiVincenzo had a profane tweet with racist rap lyrics surface on the Internet right after he helped the Wildcats win a national title.

The Oklahoma athletics department did not immediately respond to an inquiry by USA TODAY Sports regarding the tweets late Saturday night or early Sunday morning.

Murray, also a baseball player drafted ninth overall by the Oakland Athletics this past summer, plans to report to spring training in 2019 after his collegiate football career concludes. Oklahoma faces Alabama in the College Football Playoff on Dec. 29.
