Dan Mullen has been at the American Football Coaches Association annual conference in San Antonio, Texas since Sunday.
Mullen will return to Mississippi State with a new defensive coordinator in tow. Peter Sirmon will join the Bulldogs’ staff, according to a report from the Los Angeles Times.
Sirmon replaces the vacancy left by Manny Diaz as defensive coordinator and linebackers coach. Diaz left after one season to take the same positions at Miami.
Sirmon comes to Starkville from USC, where he has worked as the Trojans’ linebackers coach, recruiting coordinator and associate head coach of defense for the past two seasons.
While at USC, Sirmon helped sign back-to-back top 10 recruiting classes including the nation’s No. 1 class last year according to Rivals.com.
The 38-year old has also been linebackers coach at Washington (2012-13), Tennessee (2011) and Central Washington (2008). Sirmon served as a graduate assistant at his alma mater, Oregon, in 2009 and also Tennessee the following year.
The Walla Walla, Washington native started at linebacker for the Ducks from 1996-99 then went on to be drafted in the fourth round by Tennessee. Sirmon spent seven years with the Titans and started 54 games during his pro career.
Sirmon is the third former NFL player coaching Mullen’s defense joining former Super Bowl champions Deshea Townsend and Terrell Buckley.
Mississippi State has not confirmed the hires of Sirmon or Buckley.
