CB Colvin playing hurt for Sooners headed into Bedlam game vs No. 6 Oklahoma St

The pain comes and goes for Aaron Colvin.

The Oklahoma cornerback's injured shoulder can flare up unexpectedly. It hurts worse when it's cold and it's going to be frigid Saturday when No. 18 Oklahoma (9-2, 6-2 Big 12 Conference) plays at No. 6 Oklahoma State (10-1, 7-1).

But Colvin doesn't regret his decision to bypass the NFL draft and return for his senior season with the Sooners. Games like the Bedlam showdown are what he came back to Oklahoma for and he plans on toughing it out until the football season ends.

Colvin says he returned to Oklahoma to win as many games as he could and that he wants to have no regrets when he leaves Oklahoma.

Oklahoma coach Bob Stoops says Colvin, a first-team All-Big 12 selection last season, is one of the best defensive backs in the program's history.
