Here's the latest from the Globe's Gary Dzen:
Pierce is moving around the court very well. He’s going through his normal routine of moving around the perimeter and shooting three-pointers. He seems to be getting good elevation on his jump shot. He hasn’t limped once in the 15 minutes or so I’ve been watching him.
After he was finished taking threes, Pierce took some fadeway jumpers off the dribble. Again, Pierce didn't seem hampered by his knee.
Let's hope the knee holds up. Perkins says he going to try and play, although Doc Rivers wanted to see how Perk looked during warmups.
