Deng, averaging 18.0 points, missed his fifth straight game Friday night when Chicago played Cleveland after re-injuring his calf earlier in the week in Dallas. Coach Vinny Del Negro says Deng's calf locked up while jogging and an MRI showed more fluid than there was previously.
The Bulls also were without All-Star point guard Derrick Rose, who missed his fourth straight because of a sprained left wrist he sustained in a collision with Orlando's Dwight Howard. He is a gametime decision for Saturday at Philadelphia, as is center Joakim Noah, who has missed the past 10 games with plantar fasciitis in his left foot. Del Negro says Noah will get limited minutes "at most" if he's able to play.
The injuries come at the worst possible time for the fading Bulls, who have dropped nine in a row during a tough stretch in the schedule.
