LAS VEGAS • No. 12 Utah pounded a limping, bloodied Caleb Williams and roared past No. 4 Southern California 47-24 on Friday night to win the Pac-12 Championship and put USC’S College Football Playoff hopes in doubt.

The loss by the Trojans (112) could open the way for Ohio State (11-1) to take their spot in the playoffs. USC is fourth in the CFP rankings, the Buckeyes are one step behind.

Ohio State had to be Utah’s biggest fan. The Buckeyes move up in playoff consideration, with 12-0 Michigan at No. 2 with the Big Ten championship game on Saturday, that would give the Big Ten conference two playoff teams for the first time. It also would extend the Pac-12’s playoff drought — Washington in 2017 is the last team from that conference to make the playoffs.

Utah (10-3) is heading to the Rose Bowl, but the Utes already were going there regardless of the outcome of the title game. They are responsible for USC’S only losses, having edged the Trojans 43-42 on Oct. 15 in Salt Lake City.

The Utes rolled up 533 yards of offense in the rematch, and Cam Rising passed for 310 yards and three touchdowns.
