Oklahoma football coach Bob Stoops says it's doubtful starting middle linebacker Ryan Reynolds will play in the Sooners' rivalry game this week against No. 11 Oklahoma State.
Reynolds strained his hamstring in the Sooners' 41-13 loss at Texas Tech on Saturday and was replaced by Austin Box.
The Sooners will also be without center Ben Habern, who had surgery Saturday night after breaking his left leg. Stoops said Monday on the Big 12 coaches' conference call that Habern's recovery is expected to take three months.
He's the third offensive lineman to suffer a season-ending injury this season for Oklahoma.
Stoops says defensive tackle Adrian Taylor is expected to play against the Cowboys with an undisclosed injury.
