For the Celtics, the sight of Antoine Walker and Paul Pierce nursing injuries on the sideline at practice would normally be a major cause for alarm. But Walker, who sat out yesterday's workout with a groin pull, and Pierce, sidelined midway through practice after suffering a sprained right foot, said they would be good to go tonight when the Celtics host the Orlando Magic at the FleetCenter.

``I'll be playing that game for sure,'' Walker said after the Celtics worked out at The Sports Authority Center in Waltham for the first time since returning from their West Coast trip early Monday morning. ``I'm a little sore, but (sitting out) was more precautionary than anything.''
