LOUISVILLE, Ky. (AP) Louisville defensive coordinator Peter Sirmon has resigned after one season with the Cardinals.
Coach Bobby Petrino thanked Sirmon for his work with the program and wished him well Friday in a brief release. Sirmon came from Mississippi State last year to replace Todd Grantham, who left to succeed Sirmon with the Bulldogs.
Louisville struggled under Sirmon last fall, allowing 388.1 yards per game to rank 62nd nationally in FBS. Though injuries to several starters thinned the Cardinals' depth, they held just three opponents below 300 yards last season. Louisville allowed a season-high 625 yards at Wake Forest and 613 against Clemson in Atlantic Coast Conference losses to both schools.
