Florida linebacker Ronald Powell is leaving school early and entering the NFL draft.
Powell, a 6-foot-4, 244-pound junior from Moreno Valley, Calif., was the nation's top high school recruit in 2010. He missed the entire 2012 season after twice tearing the anterior cruciate ligament in his right knee.
He returned to play in 11 games last season, leading the team with four sacks. He finished his college career with 84 tackles and 11 sacks.
Coach Will Muschamp says "it's been well documented the hardships he has had to overcome and he has always kept a positive attitude."
Powell is the third Florida player to leave school early, joining cornerbacks Loucheiz Purifoy and Marcus Roberson. Defensive tackle Dominique Easley, who could have returned for another season, also turned pro.
