Vinny Del Negro revealed that Luol Deng will be out at least another two to three weeks.

"Luol is gonna be out two to three weeks probably," Del Negro said. "Luol's gonna be out a while."

As the Chicago Sun-Times reported from Dallas on Thursday, Deng was limping noticeably after working out before the game.

"[Deng] tried to warm up a little bit against Dallas," Del Negro said. "He was feeling better every day and thought he was getting close and then he started doing some straight ahead jogging and it really swelled up on him, so it's gonna be two or three weeks. Hopefully, two, but he has more inflammation now than he had before, so that's a setback. He's definitely gonna be out for a little bit."
