No. 4 Oklahoma will be without another key defensive starter for its bowl game next week.
Turner-Yell has been a key member of the Sooners' secondary, with his 75 tackles second on the team. The sophomore also has three passes defended and a forced fumble while starting each of the team's 13 games.
The Football Brainiacs first reported that Turner-Yell would miss the game due to the injury.
The Sooners' defense already was bracing for the loss of starting defensive end Ronnie Perkins, one of three players suspended earlier this week for the LSU game, sources confirmed to ESPN. Perkins has been Oklahoma's most consistent pass-rusher this season with 38 tackles, 13.5 tackles for loss, six sacks and six quarterback hurries in 13 starts.
