Trevor Ariza will be listed as questionable for Monday's game against the Boston Celtics with back spasms, per the Houston Chronicle's Jonathan Feigen
Ariza was hit with spasms late in Friday's game against the Denver Nuggets. After a timeout late in the game, Ariza collapsed on the sideline and after trainers tended to him for a few minutes, he would make his way back to the locker room. With the time left in the game and the score, there was no chance he was going to make it back in, even if he was able to play.
