The Cowboys have reportedly let the third-year coach's contract expire.
The Dallas Cowboys will not renew the contract of assistant head coach/defense Monte Kiffin, allowing the deal to expire after three years, according to David Moore of the Dallas Morning News on Tuesday.
Kiffin was hired in 2012 as defensive coordinator to guide the team's transition from a 3-4 defense to 4-3 scheme. The team struggled to make the change. Dallas finished 8-8 in 2013 and missed the playoffs.
During that season, the Cowboys allowed the most yards in the league and had the third-worst defense in league history.
Prior to last season, Ron Marinelli was promoted to defensive coordinator while Kiffin moved to assistant head coach for defense. However, according to Moore, Kiffin's role was minimal.
Kiffin did attend the Pro Bowl in Arizona last month with team's coaching staff, one of his final actions with the club.
Kiffin's coaching career extends back to 1966, and he has worked in various capacities with a number of college and NFL teams.
While with the Tampa Bay Buccaneers from 1996 to 2008, he coached the team to a Super Bowl victory in 2002, with his defense leading the league in yards and points allowed as well as interceptions. The Buccaneers had a top-10 ranked defense in 11 of Kiffin's 13 years with the team.
Kiffin will turn 75 this month and has said that he hopes to continue coaching.
