From NBA.com:

"Artest originally was supposed to sit out with a sore right knee. But after the pregame shootaround, he decided to play and came through with 31 points and nine rebounds."

I didn't even know he was hurt.

Bender, however, did seem to do pretty well when he was in. Gave us a quick surge, really. Then we didn't see him again. I'm assuming because of the injury, but don't really know for sure.
