Oklahoma announced the team granted junior Trevor Knight a full release on Dec. 11.
Knight was the back-up to junior Baker Mayfield at the beginning of the year. Coach Bob Stoops revealed Cody Thomas was No. 2 on the depth chart, however, in OU's final regular season game on Nov. 28.
“In the end, Cody was the back-up in our last game," Stoops said. "Cody Thomas was our back-up in the Oklahoma State game and that’s how I imagine we’ll do it this game (against Clemson) as well.”
Thomas has participated in two games this season — both were on the road against Kansas State and Kansas. Against the Wildcats, he completed one pass on one attempt for a yard.
As the temporary starter for the injured Knight in 2014, Thomas completed 30-of-66 attempts and threw for 342 yards, two touchdowns and four interceptions .
Stoops indicates the sophomore will likely serve as OU's second-string quarterback in the team's College Football Playoff seminal match-up against undefeated Clemson.
The head coach also noted redshirt freshman center Alex Dalton ruptured an ACL at Stoops' Wednesday press conference.
Junior running back Daniel Brooks, freshman defensive end Gabriel Campbell and freshman safety Prentice McKinney will not be available for the bowl game either due to academic issues.
Plus, redshirt freshman Marcus Green is no longer on OU's roster and will seek a transfer. Green played in eight games in 2015 and recorded nine tackles.
