Hardened by past questions about his toughness and buoyed by the Bulls' championship potential, an upbeat Luol Deng will try to play through a torn ligament in his left wrist that sources say doctors suggested he have surgery to repair.

"I know it sounds terrible, but I really think I'll be fine," Deng said.

Deng even is telling teammates he hasn't ruled out playing in Sunday's game against the Heat, though that seems unlikely after coach Tom Thibodeau conceded Deng is "going to be out awhile."
