Wyoming defensive coordinator Chris Tormey was fired Tuesday and replaced by defensive line coach Jamar Cain.
Head coach Dave Christensen announced the move. Tormey will be paid for the final two months of his contract, the school said. Wyoming is 93rd in points allowed in the Football Bowl Subdivision at 31.8 per game.
"I felt that we needed to make a change at this time to give our football team and the young men on it the best opportunity to win our remaining four regular-season games," Christensen said in a news release. "The last two weeks, our defense has not performed up to the expectations of our coaching staff, our players, nor our fans."
The Cowboys lost to San Jose State 51-44 last week after leading the Spartans 23-7 early in the second quarter. Wyoming was on the short end of a 52-22 score against Colorado State on Oct. 19.
