Bulls coach Vinny Del Negro isn't thrilled with the play of his team so far this season.

Chicago edged passed Milwaukee 83-81 on Tuesday night.

Bulls forward Tyrus Thomas, who didn't receive a contract extension from the team prior to Monday's deadline, was sent home on Tuesday with the flu.

There were rumors that Thomas was moping about his poor start to the season and the lack of a long-term contract, but he was legitimately sick. Del Negro refused to single him out while talking with the media.

"I'm unhappy with the play of our team," he told the Chicago Sun-Times. "I'm not gonna talk about guys individually like that, but everyone needs to pick it up a little bit."

When asked if Thomas, who didn't play in the fourth quarter of a game against Miami this past weekend, was unhappy with his playing time Del Negro didn't budge.

"I haven't seen Tyrus. He's sick; I haven't seen him all day. Next time I see him, if something's on his mind, he knows where to find me and we'll talk."
