BOULDER — Mel Tucker's 3-1 Colorado Buffaloes returned from a weekend off Monday to begin preparations for Saturday's home game with 3-1 Arizona at Folsom Field (2:30 p.m., Pac-12 Network).
Those preparations mean the Buffs will spend the week getting ready for two quarterbacks, as they don't know who Arizona coach Kevin Sumlin will trot out to take the Wildcats' first snap of the game.
Last week, Arizona saw freshman Grant Gunnell start in place of injured senior Khalil Tate (sore hamstring) and lead UA to a 20-17 win over UCLA. Gunnell completed 29 of his 44 attempts against the Bruins for 352 yards and a touchdown, and Monday earned Pac-12 Freshman of the Week honors for his efforts.
