Lakers forward Ron Artest suffered a concussion and injured his left elbow after falling at his home.

Artest didn't travel with the Lakers to Saturday's game in Sacramento after tripping over a box and falling down a flight of stairs at his home on Christmas night. He was treated at UCLA Medical Center, undergoing a CT scan and receiving stitches in the back of his head and his elbow.

A neurologist examined him on Saturday and confirmed he had a concussion, the team said. Artest is day to day.

Asked his interpretation of Artest's injury, Lakers coach Phil Jackson responded: "What do you mean, 'What's my interpretation?' What's that supposed to mean?

"Let me see, my interpretation is that an accident happened, he fell down, he ended up in the hospital, and he came out with some stitches. Other than that, I can't add anything to it."
