Stanford won’t have starting quarterback K.J. Costello when the No. 23 Cardinal visit Southern California in Los Angeles on Saturday.

Costello, who was hit in the head on a scramble out of the pocket with 10 seconds left in the first half of Stanford’s 17-7 home win over Northwestern on Aug. 31, had been listed as questionable this week to face the Trojans.

Head coach David Shaw said Thursday that Costello, a senior, won’t play, opening the door for Davis Mills, a junior, to make his first career start.

Mills completed 7 of 14 passes for 81 yards with no touchdowns or interceptions in relief of Costello, who threw for 152 yards and a touchdown on 16-of-20 passing.

Costello, a second-team All-Pac 12 preseason selection, threw for 3,540 yards and 29 touchdowns with 11 interceptions on 269-of-413 passing in 2018.

Mills was 0-for-2 passing in his only other game action, the Cardinal’s 30-10 win over the University of California Davis on Sept. 15, 2018.

The hit on Costello by Northwestern’s Earnest Brown generated controversy because Brown was not called for targeting on the hit, even though Costello was giving himself up at the end of his run. Brown was penalized on the play, but referees did not eject him upon review.
