The Daily Herald is reporting that Bulls Forward Ron Artest isn't so sure.  "Mike knows what happened," Artest said. "Maybe it was me, but somebody said A.J. I don't even know what happened. If anything, it probably was me. I want to find out, too."  Everyone saw that MJ was hurt, but it seems no one knows how, or at least are not saying so.  "I'm not sure what happened," Artest said. "I was just guarding him. I was just trying to get position because he was posting me up. I don't even recall him stopping for a brief second. Mike probably won't show any pain. I read it in the paper (on Saturday) and was like, 'Man, Mike's ribs got broke. How'd his ribs get broke?"
