CLEVELAND — Gilbert Arenas says he won't play again this season because of problems with his surgically repaired knee.

Arenas announced the decision today just before Game 5 of the Washington Wizards' first-round playoff series against the Cleveland Cavaliers.

The three-time All-Star missed the past two days of practice then decided along with the team trainer that he would not play again this season.

Arenas missed 66 games during the regular season and an MRI taken before Game 3 revealed that his surgically repaired left knee has a bone bruise and a pinched nerve.

His final shot of the season was a potential game-tying 3-pointer at the end of Game 4 against Cleveland.
