Sources - Winless Colorado Buffaloes fire HC Karl Dorrell, DC Chris Wilson

Colorado has fired head coach Karl Dorrell in the wake of the Buffaloes' 0-5 start to the 2022 season, sources told ESPN.

The school also dismissed defensive coordinator Chris Wilson, per sources. The two coaches were informed Sunday.

Offensive coordinator Mike Sanford will serve as interim coach, according to sources. Sanford is the former head coach at Western Kentucky, where he went 9-16 in two seasons (2017-18).

Gerald Chatman is expected to be named the interim defensive coordinator, according to a source.

Colorado's latest loss was a 43-20 defeat to Arizona on Saturday. The 23-point loss was the closest game Colorado has played so far this season. TCU trounced Colorado 38-13 in the opener, and the Buffaloes haven't really been competitive in any games.

Dorrell was in his third season at Colorado. He went 4-8 last year after a solid debut (3-1) during the COVID-19 season of 2020. Colorado suffered significant losses before this season to the transfer portal.

Dorrell finishes his time in Boulder with an 8-15 record in 23 games.
