Tyrus Thomas missed this morning's shootaround with the flu.
Although there is still a chance Thomas could play tonight against the Milwaukee Bucks at the United Center, coach Vinny Del Negro said rookie Taj Gibson will start at power forward regardless.
Thomas wasn't at the Berto Center when the Bulls' shootaround ended, but Del Negro said Thomas saw trainer Fred Tedeschi when he arrived before the shootaround began and was sent home.
"[Thomas] wasn't feeling very well this morning, Fred said," Del Negro said. "We'll see how he feels tonight."
