Luol Deng confirmed to the Chicago Tribune that he had suffered more pain in the stress fracture in his right tibia after a recent workout.

"I haven't even sprinted yet," Deng said. "But even if I'm capable of getting back to play five or 10 minutes, that could help. These guys have been playing a lot of minutes."

Deng won't return for any remaining regular season games and the playoffs now appear to be in jeopardy.
