Pierce told the Boston Globe that the foot originially began to bother him a week ago but flared up on Sunday. He was just 0-10 from the floor, the worst shooting performance since his rookie season. Pierce is also suffering from a sprained right hand, which he injured in practice.
"I think that really explains my tentativeness and my off shooting,'' Pierce said. "I told [coach] Doc [Rivers], I really didn't have it, but I tried to grind it out, and thank goodness we came out with a win.''
Pierce is just the latest injury for the Celtics, with Marquis Daniels, Shaquille O'Neal, Jermaine O'Neal and Delonte West already out. Hopefully the injury isn't too serious because as CelticsBlog points out, he may not have much time to rest: "But with the lack of depth already at the SF position, there aren't a lot of opportunities for Pierce to rest it."
No word yet on what this means for Pierce's availability in this weekend's NBA All-Star Game.
