Matt Barnes will undergo an MRI to reveal the extent of the damage to his sprained right knee.

He suffered the injury during the Lakers' victory over the Hornets on Friday night and Phil Jackson is "concerned" that it may be serious.

"I'm going to have an MRI, and then we'll set up a timetable," Barnes said after the game. "Any time you can walk, it's a good sign ... so just stay hopeful."
