At practice Monday, Boozer "tweaked" the sore hamstring that kept him out the whole preseason.
Under new NBA rules, the Jazz can add and delete players from their active roster up to one hour before tip-off of each game.
Robert Whaley was included on the active roster, but he won't play Wednesday. Instead, he will be serving the first game of a two-game suspension for punching Laker center Adam Parada last week in Anaheim.
Boozer, the Jazz's leading scorer from a year ago, indicated he might also miss Friday's game at Golden State and Saturday's game at home against Phoenix to ensure the injury doesn't recur.
The hamstring is greatly improved but not completely healed, Boozer said, and the prospect of re-aggravating the injury might cause him and Jazz trainer Gary Briggs to remain cautious about his health.
"We have to ask, is it better to come right back and play, and worry about, if you came back too soon, maybe you make it worse," Boozer said. "Or do you take a couple of games, get another week of solid practice without hurting it so then you know [it's healed]?"
