With an MRI scheduled this morning to determine the gravity of his knee injury, Andrew Bynum doesn’t seem as worried as the rest of Laker Nation. From the OC Register: “Andrew Bynum said his hyperextended right knee will be fine by the start of the postseason. He insisted it was ‘all right.’ He called it a set back but he plans on being in the lineup when the Lakers open the playoffs either Saturday or Sunday. ‘It’s not really that bad,’ said Bynum as he walked stiff-legged out Staples Center. ‘It was painful right when it happened but it’s not that bad right now. … I’ll take pictures tomorrow to make sure. Bynum is scheduled to have an MRI at 11 a.m. Wednesday to examine the extent of the injury, which happened when he stepped on DeJuan Blair’s foot while running back on defense in the second quarter of the Lakers’ 102-93 victory against the Spurs. Phil Jackson wasn’t as optimistic. ‘He could be out a couple of games,’ Jackson said. ‘There could be a bone bruise involved when you hyperextend the knee. His reassurance was saying ‘I’m going to be OK.’ I think that he might have an idea about it because he’s been through this before.’”
