Colvin said he was in a “ton of pain” against Kansas State, and that he knows he won't be 100 percent by the time the Sooners travel to face the red-hot Cowboys in Stillwater.
Asked if the shoulder weighs on his mind when he's going to make tackles, Colvin admitted that it does.
“As much as I would try to deny it and say that it doesn't, it does,” Colvin said. “There's always a possibility of doing something worse to it, or whatever it is that's already done. It's always in the back of your mind, but you've gotta try your hardest not to think about it.”
Colvin considered skipping his senior season at Oklahoma and entering last April's NFL Draft, and said he isn't about to let a nagging shoulder injury keep him from finishing out his senior season.
“It can be tough, but this is why I came back,” Colvin said. “I'm a competitor at the end of the day. I can't sit on the sideline and just watch something. If I don't give it my all, then I'm gonna have regrets. That's one of my biggest things is I don't wanna have any regrets when I leave this university.”
