Brett Diersen, a defensive line coach with extensive Midwest ties, enters his second season as defensive line coach at Northern Illinois University in 2013.

A year ago Diersen was tasked with rebuilding a defensive line that lost three of four starters from the 2012 MAC Championship team. Fortunately, a key player from that 2012 defensive line, noseguard from the 2012 team, Ken Bishop returned for his senior season. Under Diersen's tutalge, Bishop made 70 tackles, including seven tackles for loss, and two interceptions on the way to becoming a fifth-round draft pick by the Dallas Cowboys in the 2014 NFL Draft.

Diersen spent the 2012 season at Florida Atlantic University where he coached the Owls' defensive line and served as special teams coordinator under head coach Carl Pelini. In 2011, he was the defensive ends coach and recruiting coordinator at Indiana after spending the 2008-10 seasons on the University of Nebraska coaching staff, where he assisted with the defensive line and special teams.

The connection between Carey and Diersen dates back to 2000 when Carey took over as offensive coordinator and offensive line coach at Wisconsin-Stout, where Diersen was a graduate assistant on a Blue Devils team that went into the Division III playoffs undefeated. After coaching the defensive line, outside linebackers and special teams at the University of Dubuque from 2001-03, Diersen returned to UW-Stout as defensive coordinator in 2004 and was reunited with Carey. The two remained with the Blue Devils through 2006.

A native of Appleton, Wis., Diersen spent the 2007 campaign as defensive line coach at Minnesota State-Mankato before going to Nebraska the next season. He was on the Cornhuskers' defensive staff for three seasons, and Nebraska ranked in the Top 10 nationally in pass efficiency defense, passing defense and scoring defense in 2010 and led the nation in scoring, pass efficiency and red zone defense in 2009 behind Ndamukong Suh, who was named the Associated Press National Player of the Year and won the Bronko Nagurski, Rotary Lombardi, Outland and Chuck Bednarik awards.

As a player, Diersen was a three-time all-conference defensive end at Huron (S.D.) University from 1994-98, where he earned his bachelor's degree in 1998. He added a master's degree in education from UW-Stout in 2005.

Diersen and his wife, Jenna, welcomed son Brody in August 2013.
