Bulls guard Jimmy Butler out 3-4 weeks with knee sprain

CHICAGO (AP) Bulls guard Jimmy Butler will miss the next 3-4 weeks with a strained left knee and will be replaced in this weekend's All-Star Game by Chicago teammate Pau Gasol.

The Bulls said Tuesday that Butler has begun rehabbing his knee and will focus on conditioning over the next few weeks. He was injured during Friday night's game at Denver.

Butler was an All-Star reserve. Gasol will replace him on the East team and make his sixth appearance in Sunday's showcase event during his 14-year NBA career.
