Z-Bo can’t play (or sit properly, I’m guessing), and his concern is that his tailbone may be fractured. Ouch. The Commercial Appeal reports: “Randolph said team doctors will look at magnetic resonance imaging Monday to determine if his condition is worse than originally diagnosed. Randolph is sitting out with a bruised tailbone but the fear is he has a fracture. ‘I’m still in a lot of pain,’ Randolph said. ‘I can’t jump without pain. I want to be able to play against the (Los Angeles) Lakers (Tuesday). I just hope there isn’t a crack.’”
