The status of Bulls forward Luol Deng is uncertain as the Bulls tackle the New Jersey Nets in a critical game tonight at the United Center.

Deng was sent to the hospital on Monday because he hadn?t shaken all the cobwebs from a mild concussion suffered two days earlier.

?Luol Deng still has some symptoms from his concussion,? trainer Fred Tedeschi said at the Berto Center. ?Primarily a headache. We sent him down to Rush Medical Center to get re-evaluated by Dr. (Kathy) Webber. We?ll just take it from there.?

Tedeschi didn?t want to place a probability on Deng?s availability, but he did say he?d like to see Deng symptom free for at least 12-24 hours. The second-year forward will be re-evaluated this morning.
