After being sent home from Thursday night's Bulls' loss to the Nets at the United Center, All-Star small forward Luol Deng is back in a Chicago-area hospital emergency room Friday.

As first reported by prior to Thursday's game, a spinal tap was performed on Deng on Wednesday to ensure that he didn't have a case of meningitis--the tests were negative and he does not have that specific illness--but after missing two consecutive days of practice, he arrived at the United Center for Game 6 of the first-round series and was not cleared to play by the team's medical staff.

Besides clearly being under the weather, Deng was also suffering from the side effects of the aforementioned procedure, which draws fluid from a person's brain and back, then heavily impairs their ability to function, as was evidenced by the league's back-to-back minutes-per-game leader wobbling down the arena's hallway.

After the Bulls' practice Friday afternoon at the Berto Center, Bulls head coach Tom Thibodeau said he was uncertain as to whether Deng would travel with the team to New York for Saturday's Game 7 against the Nets.

"He's still not feeling well, so we'll see," Thibodeau said. "I'm not sure everything he's had. He's had an examination by the doctors, treatment by the doctors."

Aside from Deng, the Bulls were without starting point guard Kirk Hinrich, who was suffering from a left-calf injury, not to mention the fact that Taj Gibson and Nate Robinson -- the latter was seen vomiting on the sidelines during the contest -- were dealing with flu-like symptoms in Game 6.
