Bobcats forward Emeka Okafor had an MRI exam on his sprained right ankle Tuesday in Charlotte and did not accompany the team to Chicago.

The Bobcats prevailed 105-92 in Chicago.

Okafor, averaging 12.9 points and a team-high 10.1 rebounds, was injured late in the third quarter of Monday's overtime victory over Sacramento when he collided with the Kings' Francisco Garcia while going for a rebound. He rolled around momentarily, grasping his leg, and was unable to put pressure on it as he left.

The results of the MRI were not immediately available.

"I don't have the courage to inquire right now," Charlotte coach Bernie Bickerstaff said before Tuesday's game.

Besides Okafor, starting guard Kareem Rush (sprained left index finger), forward Melvin Ely (flu-like symptoms) and center Jake Voskuhl (sprained right ankle) stayed home. Rush, second on the team with 13.5 points per game, aggravated an injury that has bothered him on and off for about a month during Monday's game.

The Bulls were without leading scorer Luol Deng, who bruised his right knee in Saturday's victory over Boston. An MRI taken Monday was negative.
