CLEVELAND (AP) Reggie Rucker's sentencing in a charity theft case has been delayed as the former Cleveland Browns wide receiver participates in a study of long-term symptoms of traumatic brain injuries and awaits another test in June.

His attorneys say Rucker suffered multiple concussions while playing football and that the effects of such injuries - and the upcoming test - might help explain his crimes.

The 68-year-old Rucker has pleaded guilty to stealing from two children's charities to pay his gambling debts and personal expenses. A plea agreement calls for him to serve about two years in prison.
