Charlotte Bobcats forward Emeka Okafor is expected to be out at least another five weeks with a sprained right ankle that has already cost him 19 of the last 20 games.

The reigning NBA Rookie of the Year originally sprained his ankle Dec. 19 and missed eight games. He returned on Jan. 10, but was re-injured in the Bobcats' double overtime win over Houston. Charlotte hasn't won a game since.

Also, forward Gerald Wallace (knee bruise) and guard Keith Bogans (knee sprain) are expected to be out another two to four weeks with their injuries.
