NORMAN, Okla. -- The big news of the day was Bob Stoops revealing that Stacy McGee has been suspended indefinitely for violating university policy. McGee was starting at the three-technique alongside Casey Walker and Jamarkus McFarland, who were manning the nose-guard spot. Redshirt freshman Jordan Phillips was backing up McGee at the three-technique.
Walker continually stressed the need for him to stay healthy this season. With the news of McGee’s suspension, Walker becomes even more important for OU. Walker and Jamarkus McFarland are the Sooners' top two defensive tackles with limited game experience behind that senior duo.
Walker has played in 21 of 27 games in the past two seasons as he’s been hampered by injuries. He played through labrum and thumb injuries in 2011, playing in 12 games while starting eight.
