Bulls' Butler expected to be out almost a month with injury

The Bulls are definitely going to miss him.

Chicago Bulls shooting guard Jimmy Butler is expected to miss three to four weeks with a strained left knee. Butler came down hard on his knee against the Denver Nuggets February 5 after a hard foul. He had to be carted off the floor and the injury will keep him from participating in this weekend's NBA All-Star activities. Butler was selected as a reserve to the East squad by the Eastern Conference head coaches.
