Washington Wizards point guard Gilbert Arenas sat out Tuesday night's game against New Jersey with an ailing back.

Arenas bruised his lower back Saturday night when he crashed to the floor after his shot was blocked from behind by Darius Songaila in a loss to Chicago. Arenas had already been bothered by a sore back, and he said after the game that his "whole right side'' was aching.

Arenas played the next day, missing 19 of 24 shots in a loss at Miami. He did not practice Monday and did not take part in the shootaround Tuesday morning.
