SACRAMENTO -- Ron Artest suffered a concussion after a fall at home Friday night, the Lakers announced today. Artest will not be available to play in tonight's game against the Sacramento Kings. He has improved since tripping over a box at home and falling down a flight of stairs. He was treated at the emergency room at UCLA Medical Center and received stitches to close wounds on his head and left elbow. He was examined by a neurologist today and will return for further examinations daily until he is cleared to return to the active roster.
