"Jimmy's still sore," Thibodeau said, according to the Chicago Tribune. "We'll see where he is (Thursday)."
Butler is scheduled to play in his first career All-Star Game on Sunday and is also slated to take part in the Skills Challenge on Saturday. The Bulls' last game before the All-Star break is Thursday against the Cleveland Cavaliers.
Butler had five points, two rebounds and two assists in 22 minutes on Tuesday before he was injured.
