College football fans everywhere were taken by surprise late Sunday night and early Monday morning upon learning that Tennessee coach Jeremy Pruitt had fired Volunteers defensive line coach Jimmy Brumbaugh. A new report says Brumbaugh was fired Saturday during UT’s loss to Kentucky.

“A source close to the UT program tells KSR that Tennessee head coach Jeremy Pruitt fired assistant coach Jimmy Brumbaugh during the game on Saturday,” Zack Geohagen of Kentucky Sports Radio wrote Wednesday. “Pruitt let Brumbaugh go while the game was still being played, confirming it after it was over.”

Many fans were puzzled why Pruitt fired a defensive assistant when the Volunteers’ offense was to blame for multiple Wildcats scores. Brumbaugh replaced former Tennessee assistant Tracy Rocker who is now on the South Carolina staff. It was reported that Brumbaugh could be receiving more than $830,000 from UT in buyout payments.

Brumbaugh was a Kentucky defensive assistant from 2013-16. Pruitt, who has multiple seasons of experience as a defensive coordinator, is now coaching the Tennessee defensive line himself.

Vols defensive linemen will play their first post-Brumbaugh game on Saturday against No. 2 Alabama. The game is set for a 3:30 p.m. ET kickoff as the “SEC on CBS” showcase game of the week.
