Young Andrew hurt his elbow in the closing moments of last night’s thrilling victory against Houston, and an MRI today will determine the severity of the injury: “Andrew Bynum suffered what’s initially being called a sprained right elbow on the Lakers’ final possession of overtime on Wednesday when he was fouled going up for a shot. The injury didn’t prevent Bynum from sinking the second of two free throws to break a tie at 102, but he will have an MRI on it on Thursday and struggled to get dressed after the game. ‘I can’t really lift my arm right now. I have to get it checked out,’ Bynum said. ‘I swear I hope it’s not serious.”‘
