Just when you think Lamar Odom's season can't get any worse, it does.

Having played only 29 games with the Clippers and scheduled to wear a cast on his sore right wrist for two more weeks, Odom dunked a basketball in Thursday's shoot-around, stepped on the ball, fell and sprained his right ankle.

X-rays were negative, but the ankle was put in a soft cast. This injury is expected to keep him out for two to four weeks.

"I'm sad," said Odom. "There's nothing I can do about it. It was a freak accident. I just want to do everything I can to get back as soon as possible."
