MILWAUKEE (AP) – Dallas forward Caron Butler left the Mavericks’ game against Milwaukee in the first quarter Saturday night after injuring his right knee.

After Dallas’ Jason Kidd hit a shot, Butler went down to the floor grasping his knee. He rolled over onto his stomach as play continued before Dallas was able to call a timeout.

The training staffs from both teams assisted Butler, who slapped the floor in frustration. Two minutes later, Butler — from nearby Racine — was helped to his feet and limped to the locker room under his own power.

The Mavericks said he would miss the rest of the game.

In April 2007 at the Bradley Center,Butler broke his right hand while with the Wizards when he was challenging a shot at the backboard. He missed the rest of the season.
