If the Bulls are going to pull off a win in Game 7 of their series with with the Nets in Brooklyn on Saturday, they'll have to do so without their most durable, reliable player. 

Luol Deng has been ruled out as he's still in the hospital recovering from a spinal tap he had Thursday. 

Deng took to Twitter to explain that he missed Game 6 because of the spinal tap, and not from the flu. 

"As a result of the spinal tap I suffered the worst headache I've ever experienced and been the weakest I've ever felt," Deng tweeted. "Yesterday I was unable to walk or even get out of bed. I made it to the UC and was sent home. (Friday) morning my symptoms worsened."

Kirk Hinrich will also miss Game 7 with a bruised calf, the Associated Press reported. Hinrich sat the last two games.
