Oklahoma offensive lineman Michael Thompson entered the transfer portal, he announced Tuesday.
Thompson, a St. Louis native, signed as a four-star defensive tackle but suffered a torn anterior cruciate ligament before redshirting in 2018. He was moved to the offensive line last spring; it was seen as a fit because the Sooners and others once recruited him as an offensive lineman in high school.
He was said to be making progress after the move but will leave OU having never appeared in a game.
"I would like to say thanks to @LincolnRiley and the rest of the Oklahoma coaching staff for giving me a opportunity to do what I love and pursue my dreams but after taking some time and thinking I will be entering the transfer portal," Thompson posted to his Twitter account.
Thompson is the fifth OU player to enter the portal this season, joining Jonathan Perkins, Miguel Edwards, Starrland Baldwin and Jaqualyn Crawford.
Entering the NCAA database doesn't finalize a player's transfer, but in the portal era, A.D. Miller is believed to be the only OU player to return after toying with the idea of leaving.
