Oklahoma State freshman guard Raymond Penn has been declared out for the season with a stress reaction in his right knee. He has only played one game since Jan. 20.
Penn showed flashes of promise in his first year with the Cowboys. He averaged 7.8 points and three assists in 19 games. The 5-foot-9 guard will need to work on his shot as he rehabs: he made just 36.2% of his shots.
