BOULDER, Colo. (AP) — George King scored 21 points, including a buzzer-beating 3-pointer at the end of the first overtime, and grabbed a pivotal rebound late in the second OT to help Colorado hold off Washington State 88-81 on Thursday night.

Xavier Talton sealed the win with four straight free throws over the last 30 seconds, sending the Cougars to their 10th straight loss.

The Buffaloes (18-7, 7-5 Pac-12) were without big man Josh Scott, who sprained his ankle last weekend. With Scott went a team-leading 16.7 points and opened up things for Washington State (9-15, 1-11) in the paint.

Que Johnson scored a career-high 25 points and had the Cougars on the verge of their first road win of the season, hitting a go-ahead 3-point play with 22.4 seconds left in the first OT. But King's shot spoiled the moment.

King's fadeaway 3-pointer at the buzzer electrified the crowd. The officials reviewed the play and upheld the shot.
