Celtics coach Doc Rivers said before the game that O'Neal is also questionable to travel with the team on the upcoming four-game road trip that begins Sunday at Oklahoma City.
"I don't know if it's looking good, to be honest, but I don't know," Rivers said of O'Neal. "We'll see. I don't even know right now if we'll bring him on this road trip, let alone if he's going to play."
