OXFORD, Miss. (WOLO) -- Ole Miss senior guard Marshall Henderson has been suspended indefinitely by Ole Miss. The school announced the suspension Wednesday, for a violation of team rules. "Since the season ended, we have talked a lot about Marshall taking a greater leadership role with our team. With that comes greater responsibility, and he must do a better job of living up to the high standard we expect from him and he desires from himself," Ole Miss head coach Andy Kennedy said in a statement. Marshall was last season's SEC tournament MVP and conference score leader. Henderson is no stranger to trouble. He failed a drug test in January 2012 and was arrested on forgery charges stemming from when he was a high school senior.
