SALT LAKE CITY (AP) -- Andre Roberson had 12 points and 15 rebounds and Austin Dufault added 11 points as Colorado defeated Utah 55-48 Saturday.

The win was the second this season over the Utes, who lost 73-33 to the Buffaloes (17-8, 9-4 Pac-12) on New Year's Eve in the Pac-12 debut for both teams.

Colorado guard Carlon Brown suffered through a miserable shooting performance -- going 2 for 12 -- and finished with five points in his return to Salt Lake City, where he played three seasons for Utah.

Jason Washburn led Utah (5-20, 2-11) with 16 points and 10 rebounds. Chris Hines added 12 points on four 3-pointers.

The Utes trailed by as many as nine points in the second half, but tied the score at 44 with 4:23 remaining. Colorado then went on a 6-0 run, Dufault got a late block and the Buffs sank key free throws down the stretch to secure the win.
