Kelvin York rushed for 132 yards and two touchdowns and Trevor Reilly had a late interception to help Utah slide by Colorado 24-17 on Saturday afternoon.

In a matchup of the two teams at the bottom of the Pac-12 South, the Utes raced to a 21-0 lead before the Buffs roared back.

On fourth-and-10, Sefo Luifau completed a 14-yard TD pass to Nelson Spruce that made it 24-17 with 2:30 remaining. The ensuing onside kick bounded high over the Utah line and out of bounds.

But the Buffs forced a Utah punt that was downed at the 10 — Tom Hackett's third kick inside the 10-yard-line. Defensive end Reilly dropped back from the line and intercepted the ball at the 21. A year of frustration was evident as Reilly threw the ball high into the end zone stands before he was greeted by a horde of teammates on the sidelines.
