Oklahoma cornerback Michiah Quick, who showed promise early in the year after moving over from wide receiver, is no longer with the Sooners, Bob Stoops announced Monday.

Stoops said Quick's separation with the team was due to a violation of team rules.

Quick moved into the starting lineup to begin Big 12 play after Dakota Austin struggled and Parrish Cobb was injured.

He had eight tackles against Ohio State and a pair of pass breakups against TCU. Against Texas, he had a key pass breakup early but suffered a sprained media collateral ligament later in the first half.
