Bulls forward Tyrus Thomas injured his left arm during the weightlifting portion of the team's practice on Friday.

The team announced the injury and said that Thomas went for X-rays after practice.

"Hopefully, everything is fine," coach Vinny Del Negro told the Chicago Tribune. "I'm not even exactly sure how he got hurt yet. But he tweaked his arm a little bit and he's pretty sore."

Del Negro said that the team will determine Thomas' availability for Saturday's game against the Bobcats on Saturday.

The forward missed two games with the flu recently.
