UCLA's formula for a third appearance in the title game is simple: Defeat the Trojans on Saturday, and Stanford next Friday.
USC needs help to gain its first conference championship-game berth. The Trojans must defeat UCLA, and
Several assistant coaches in Saturday's game have worked for the rival.
UCLA running backs coach Kennedy Polamalu played for the Trojans. He coached at USC from 2000 to 2003 under former coaches Paul Hackett and Pete Carroll, and from 2010 to 2012 under former coach Lane Kiffin.
USC tight ends coach Marques Tuiasosopo was an intern in UCLA's football office in 2011 and the Bruins' tight ends coach in 2012.
Something to watch: USC, which contributed to the Shaw saga by posting a heroic story about him on its website in August, is not allowing Shaw to speak to the media.
What happens if he makes game-deciding plays in a Trojans victory?
UCLA quarterback Brett Hundley will try to become only the second Bruins quarterback to win three games in the rivalry.
Hundley has passed for 17 touchdowns, with four interceptions. The junior is ranked seventh nationally in passing efficiency. He also has rushed for 564 yards and seven touchdowns.
Last season against USC, Hundley completed 18 of 27 passes for 208 yards and rushed for 80 yards and two touchdowns in a 35-14 victory.
Hundley faces a defense that has intercepted 11 passes.
USC quarterback Cody Kessler has passed for 29 touchdowns, with three interceptions. The junior is ranked fourth nationally in passing efficiency.
Kessler completed 17 of 28 passes for 174 yards and a touchdown against UCLA last season.

Freshman JuJu Smith has 42 catches, five for touchdowns. George Farmer, Darreus Rogers and Steven Mitchell also have touchdown catches.
Tight end Bryce Dixon, who has three touchdown catches, was suspended from the Trojans' Nov. 13 victory over California for what Sarkisian described as an unspecified "student conduct issue." Dixon practiced this week but Sarkisian did not say whether he would play.
