Bears' Marshall fires back at Sapp

Chicago Bears receiver Brandon Marshall criticized former NFL star Warren Sapp for calling him a ''retard'' in a radio interview.

That struck a chord with Marshall, who has acknowledged receiving treatment for borderline personality disorder and anger management, and he fired back Monday in an online video. He says he can't discuss finances with Sapp ''because he filed for bankruptcy,'' or marriage ''because he filed for divorce.'' Marshall also says he can't speak to him about becoming a father some day because ''he's not active in his children's life.''

This was in response to an interview with the syndicated ''The Dan Patrick Show'' in which Sapp, an NFL Network analyst, blasted Marshall for ''talking about Shannon Sharpe'' and allegedly not knowing this: ''He's the first 100-catch receiver (tight end) back to back, retard.''
