Benched Tampa Bay Buccaneers quarterback Josh Freeman said he has attention deficit hyperactivity disorder and that he voluntarily entered the NFL substance abuse program more than a year ago after mistakenly taking a medication to treat the condition.

Freeman said in a statement released on Monday by his agent that he has passed all 46 drug tests he's taken for the league since once using Ritalin instead of Adderall to treat ADHD.

The fifth-year pro was benched last Wednesday after the Bucs got off to an 0-3 start that included a pair of losses on last-second field goals.
