Houston forward Ron Artest will miss the team's next two games because of a sprained right ankle.

The Rockets have so many injuries that they barely have enough players to field a proper practice.

"We've got to win games and keep our heads above water," Coach Rick Adelman said. "If we're going to have injuries like this, you just have to win as many as you can."

Artest sat out Monday's loss in Memphis, the first game he's missed this season. He had an MRI exam Tuesday that revealed damaged ligaments in the ankle, an old injury that Artest recently re-aggravated.
