It is called the Rumble in the Rockies, Utah's rivalry with Pac-12 foe Colorado.
The No. 21 Utes (7-3, 5-3 Pac-12) are hoping the Buffaloes (5-5, 2-5) are not ready to rumble and are more like the team that has been beaten the last five weeks after starting 5-0.
Utah still has its sights on a Pac-12 South title although coach Kyle Whittingham's team is without starting quarterback Tyler Huntley (broken collarbone) and running back Zack Moss (knee) for the rest of the regular season.
Despite their absence against Oregon last week, the Utes prevailed behind redshirt freshman quarterback Jason Shelley (262 passing yards) and reserve running back Armand Shyne (career-high 174 yards rushing).
