Mason Rudolph, James Washington and Chad Whitener are expected to return to Oklahoma State for their senior seasons, a source close to the program told The Oklahoman.

But a source close to Rudolph was adamant Monday night that the Cowboy quarterback has not yet made a decision and will base his choice on the draft information he receives from the NFL. Rudolph and Washington said Monday afternoon they had not received their draft grades.

Defensive tackle and first-team All-Big 12 selection Vincent Taylor remains undecided and has said previously he would make a decision about his future after the Alamo Bowl.
