Gilbert Arenas will watch the rest of the NBA playoffs from the press box. 

The Washington Wizards guard missed most of the regular season, sitting out 66 games following knee surgery.  

After missing two days of practice, Arenas declared that he was unfit to play. 

"Instead of me blocking the team from success, we just decided just go ahead and shut it down," Arenas said an hour before tipoff. An MRI after Game 3 revealed that Arenas's knee had a bone bruise and a pinched nerve.

"I'm taking four different kinds of pain pills just to play in a game, and it still doesn't work," he said. Arenas is averaging 10.8 points per game in the playoffs, putting him fifth on the team in that category.

The Wizards will try to stave off elimination Wednesday night, in Game 5 of their Eastern Conference quarter-final, against the Cleveland Cavaliers. The Wizards trail 3-1 in the best-of-seven series.
