UCLA center Kai Maiava suffered a broken left ankle on the third play of the Bruins' scrimmage Saturday night and will be lost for the season.
Maiava, a junior, will have to have surgery on the ankle, possibly to have a screw placed on the bone to help it heal. He started all 12 regular-season games last season.
Senior Ryan Taylor will move from guard to center, leaving a hole at left guard that will have to be filled.
