Colorado head coach Karl Dorrell fired offensive coordinator Darrin Chiaverini on Sunday after a 4-8 season.
The Buffaloes were 3-6 in the Pac-12, including a season-ending 28-13 loss Friday at No. 19 Utah.
Colorado ranks last in the conference in total offense (257.5 yards per game) and passing offense (131.3) and 11th in scoring offense (18.8 points per game).
Chiaverini, 44, joined the coaching staff on Jan. 1, 2016, and had one year remaining on his contract.
Before coming to Boulder, he coached at Texas Tech and UCLA following his playing career as a wide receiver at Colorado (1995-98) and in the NFL with the Cleveland Browns (1999-2000), Dallas Cowboys (2001) and Atlanta Falcons (2002).
"This was a very tough decision, especially with Darrin being a former player and knowing how much he truly cares about the program," Dorrell said. "I do appreciate all the time and investment he put in being in the positions he's been in over the last six years.
"I believe it's just time to go in a different direction," he continued. "We need a new perspective, which can bring new life and a different energy along with it. In the end, we need to do what's best for the program, and at the same time, certainly wish Darrin the best in his future endeavors."
Chiaverini is the second member of Dorrell's staff to be relieved of his duties this season. Offensive line coach Mitch Rodrigue was let go on Oct. 25.
