LOS ANGELES -- UCLA left tackle Simon Goines has undergone surgery on a broken bone in his right leg.
Receivers Grayson Mazzone and Darren Andrews also are out for the season after they were injured in the No. 22 Bruins' 38-33 loss to Arizona State on Saturday.
Goines is the latest major injury loss for the Bruins (8-3, 5-3 Pac-12), who likely will face No. 23 Southern California in their regular-season finale with three freshman starters on their offensive line.
Goines started five of the Bruins' first six games at left tackle, but missed UCLA's next four games with a right knee injury. The sophomore returned to the starting lineup against the Sun Devils, but had to be helped off the field in the second quarter.
