His coach called him a fifty-fifty shot to play. So, even if Tim Duncan does play, don't expect him to play a lot of minutes tonight against Utah, and don't expect him to be overly effective as anything more than a decoy for Tony Parker and Manu Ginobili to play off of.
If you are rooting for San Antonio to beat the Jazz, there are two things in your favor: First is that Carlos Boozer has a bad track record against the Spurs and second is the fact that the Jazz can't stop anyone from driving to the hoop lately. If Boozer plays poorly and Ginobili and Parker can slash to the rack all night, the Spurs will win this game.
Having said that, I have a gut feeling that Boozer will have a good game tonight. Without Duncan being at 100%, he should get his opportunities to work the paint. The Spurs have to lose a game at home sometime soon. This smells like the perfect opportunity.
