Luol Deng's right wrist has propelled so many true shots and slammed home so many authoritative dunks that any blemish on it is a big deal.

Both Deng and the Bulls are confident the contusion he suffered in the first quarter of Friday's 92-82 loss to the Raptors at the Air Canada Centre is minor.

Deng calmly insisted Friday's injury, which limited him to just 2 minutes 27 seconds in what team officials called a precautionary move, is unrelated to an injury during his rookie season that required late-season surgery.

"I kind of bent it backward," Deng said. "My hand was kind of behind me. I'm pretty sure it's not related to the other injury. I even wanted to go back in."
