Saints defensive coordinator Rob Ryan was fired Monday, NFL Media Insider Ian Rapoport reported, per a source informed of the team's decision. Coach Sean Payton confirmed the news to WWL Radio, the team announced.
The Saints will promote senior defensive assistant Dennis Allen to defensive coordinator, according to Rapoport.
Ryan, after amassing the No. 4 defense in football back in 2013, embarked on a quest to create the league's most versatile secondary. The Saints inked Jairus Byrd to a lucrative six-year, $54 million deal back in 2014 and handed Brandon Browner a three-year deal in free agency this year, adding him to the mix with first-round pick Kenny Vaccaro at safety.
