Bulls forward Tyrus Thomas suffered another mishap Friday afternoon. Working out in the weight room at the Berto Center, he fractured the radius in his left forearm and is expected to be sidelined 4 to 6 weeks.
X-rays confirmed the injury and he will undergo surgery Saturday at Rush University Medical Center. The surgery will be performed by team physicians Dr. Brian Cole and Dr. John Fernandez, and assisted by Dr. Mark Cohen.
In Thomas' absence, rookie Taj Gibson figures to become the full-time starter at power forward. He started the past two games while Thomas was suffering from the flu.
Thomas missed Tuesday's win over Milwaukee. On Thursday, he felt better and caught a commercial flight to Cleveland, then scored 6 points in 12 minutes during the Bulls' win over the Cavs.
When Friday's practice ended, Bulls coach Vinny Del Negro wasn't sure of Thomas' status.
“I’m not even exactly sure how he got hurt yet," Del Negro said. "He kind of tweaked his arm a little bit and got an X-ray. It’s pretty sore.
“I think he was doing some type of pull-up or whatever and kind of injured his arm a little bit. It’s just unfortunate.”
Thomas started the first three games of the season. He’s averaging 8.3 points and 5.3 rebounds.
