Colorado fires Karl Dorrell after 0-5 start

Colorado fired head coach Karl Dorrell and defensive coordinator Chris Wilson on Sunday amid a five-game losing streak to begin the season, the school announced.

Dorrell was in his third campaign and went 8-15 before his dismissal.

"I want to thank Karl for his hard work in leading our program since 2020," Colorado athletic director Rick George said. "Ultimately, however, the results on the field just did not measure up to our expectations and standards, which made it necessary for us to make this change at this time.

"It was an extremely difficult decision, and I wish Karl all of the best in his future endeavors."

The Buffaloes fell 43-20 to Arizona on Saturday, marking their fifth double-digit defeat in as many games to open the schedule. Colorado has allowed 40 points or more in four of five losses and gave up 38 points to TCU in the season opener.

Dorrell said Saturday he wasn't concerned about his job security, even though the Buffaloes lost for the 15th time in 19 contests. Colorado went 4-2 in Dorrell's first season - the 2020 campaign that was shortened by the COVID-19 pandemic.

Dorrell was the wide receivers coach and assistant head coach with the Miami Dolphins when Colorado poached him in 2020. He had one previous stint as an NCAA head coach, posting a 35-27 mark at UCLA from 2003-07.
