Stanford quarterback K.J. Costello has been ruled out of Saturday’s game at Oregon State with a hand injury, the school announced Friday.
Costello has been hampered by injuries throughout 2019. He missed a loss to USC on Sept. 7 after being hurt in the season opener against Northwestern but returned to play in losses to UCF and Oregon amid the Cardinal’s 1-3 start.
Davis Mills is expected to make his second start of the season, according to the school. Mills was 22-for-36 for 237 yards with one touchdown and one interception while filling in for Costello against the Trojans.
Costello has thrown for 471 yards with two touchdowns and two interceptions this season. His 56.4% completion rate would be a career low for the senior.
