BOULDER, Colo. -- Colorado leaned on a couple of veterans to help make up for the loss of freshman star Josh Scott, who missed a game for the first time this season after suffering a concussion.
Senior Sabatino Chen and junior Jeremy Adams combined for 21 points and Colorado pulled away to beat Utah 60-50 on Thursday night.
"Sabatino played terrific defensively and in getting the ball in the lane and making some things happen," Colorado coach Tad Boyle of Chen, who had 12 points. "He only had one assist but he made a lot of plays that led to a play that led to a basket. Jeremy Adams I thought played some critical minutes in both halves. Both those guys stepped up, and that's what you have to have when you have a guy like Josh go down."
Adams, who finished with nine points, said he and the rest of the team were well aware they would need more production from the bench in the absence of Scott.
"We've got to make up for Josh, if not by scoring then by rebounding," Adams said. "I think we did a great job."
Scott, who averages 11.4 points per game, took an elbow to the head during last weekend's loss to Arizona State in overtime and is still dealing with post-concussion symptoms.
"He's doing a lot better today than he was yesterday," Boyle said. "I don't know when he's going to get back. All I know is until he gets back, we're going to need performances like we had tonight."
Spencer Dinwiddie scored 13 points and had a key block in the late going for Colorado (18-8, 8-6 Pac-12), which gained a split of its season series with the Utes. Utah took the first meeting 58-55 earlier this month.
Jordan Loveridge had 12 points to lead the Utes (11-15, 3-11 Pac-12). Jason Washburn and Brandon Taylor added 10 points apiece.
"They went smaller (without Scott), but they have a quick team. ... They kept the ball moving," Utah coach Larry Krystkowiak said. "We struggled to get the ball inside. I was hoping we could get it in more with their small lineup, but they did a good job fighting some touches and putting pressure on our post feeds."
Andre Roberson, who is leading the nation in rebounding, had 10 points and had 13 boards for the Buffaloes. He increased his career total to 1,006. He ranks second in school history behind Stephane Pelle, who had 1,054 from 1999-2003.
"It means a lot," Roberson said of being the second Colorado player to achieve the 1,000-rebound milestone. "Coach Boyle has been preaching from day one, defensive rebounding, and I just took it to heart. I feel like it's a great accomplishment for me and I'm not done working."
Loveridge opened the second half with a 3-pointer, putting Utah in front by a point. Colorado answered with an 11-0 run that started with a putback by Xavier Johnson. Askia Booker and Chen also drained 3-pointers in the surge en route to a 41-31 Colorado lead, the Buffaloes' biggest to that point.
Dakarai Tucker hit a 3-pointer and Loveridge made a layup around a free throw by Johnson as the Utes pulled within 50-46 with 6:25 remaining.
Both teams traded baskets before Colorado got a stop when Dinwiddie swatted away Taylor's attempt at a driving layup. The Buffaloes followed up the defensive play with a putback by Roberson, giving Colorado a 55-48 lead with 3:41 left to play.
The Utes scored only one more field goal the rest of the way while Colorado hit its free throws down the stretch to secure the victory.
A dunk by Washburn gave the Utes a 28-24 lead with 3:11 left in the opening period. But the Buffaloes closed out the half by scoring the final five points, including a 3-pointer by Dinwiddie, for a 30-28 lead.
Midway through the first half, Dinwiddie's streak of consecutive free throws ended at 33 after he missed the second of a pair of foul shots. It was the third-longest streak in school history.
Cory Higgins set the school record in 2010-11 when he made 45 in a row.
