USC vs. Notre Dame score: Live game updates, college football scores, NCAA top

No. 6 USC took a 17-7 lead on No. 15 Notre Dame into halftime of their rivalry showdown as the Trojans try to pick up a critical victory for their College Football Playoff hopes. With a win Saturday and in next Friday’s Pac-12 Championship Game, the Trojans will have a strong case to make the four-team field. The Fighting Irish have been playing some of their best football as of late, though, and gave the Trojans a challenge in the first half.

Behind the play of quarterback Caleb Williams, USC took a two-possession lead into the break. Williams played a variety of roles for the Trojans in the first half. In addition to some elite quarterback play, featuring a rushing touchdown and passing touchdown, Williams also booted a 58-yard punt. On another play, he wound up as a receiver on a trick play and was called for pass interference while breaking up a potential interception. With the Fighting Irish striving to finish the regular season with a bang, and USC yearning for titles, the second half figures to be compelling theater.
