Southern Miss head coach Todd Monken has replaced offensive line coach Pete Perot with graduate assistant Grant Garner for the final two games of the season, the athletic department announced Tuesday.
The press release did not give a reason for Perot's departure. While staff changes seem likely considering the team is 0-10 this season, it's unusual for an assistant to be forced out during the regular season.
USM's struggles on the offensive line have been well documented this season with the team's quarterbacks receiving little time to throw the ball and running backs getting little room to run.
Perot, who was in his second stint at USM, was the offensive line coach at Louisiana Tech for 12 seasons prior to joining Monken's staff. Perot was the offensive line coach at USM from 1997-99.
Never miss a local story.
USM has plenty of inexperience on the line this season along with key injuries. The biggest loss was senior starting right tackle Vincent Brown, who hasn't played since the season opener due to injury.
USM is in the midst of an 0-10 season and the nation's longest losing streak at 22 games.
Southern Miss hosts Middle Tennessee State at 2:30 p.m. on Saturday.
