PASADENA -- UCLA starting quarterback Richard Brehaut fractured his lower left leg during the Bruins' game against Washington State on Saturday night and will be out indefinitely.
Brehaut left the Bruins' Pac-12 game midway through the second quarter after running two quarterback keepers. He was hit hard on the first one and appeared to have his ankle twisted on the second one. He got up limping badly, then collapsed to the ground and had to be helped off the field.
The Bruins announced after halftime that Brehaut had a broken lower left leg, giving no further specifics.
Brehaut started four of the Bruins' first six games, passing for 907 yards and six touchdowns without an interception before Saturday's game.
Kevin Prince, the starter at the beginning of the season, relieved Brehaut. Prince passed for 173 yards, including a go-ahead, 7-yard touchdown pass to Shaq Evans with 3:26 to play as UCLA rallied from an eight-point deficit in the fourth quarter for a 28-25 victory over Washington State.
