The Arizona Cardinals have made Nick Rallis the youngest coordinator in the NFL, hiring him to run their defense at the age of 29.

NFL Media's Tom Pelissero reported the Cardinals have appointed Rallis as their defensive coordinator in a move that sees him follow Jonathan Gannon to Arizona.

Gannon, the former Eagles defensive coordinator, was hired as head coach of the Cardinals days after Philadelphia lost Super Bowl LVII 38-35 to the Kansas City Chiefs at Arizona's State Farm Stadium.

It continues a rapid ascent for Rallis, who became the youngest position coach in the NFL when he was hired to coach the Eagles' linebackers in 2021.

Prior to that, he served as a defensive quality control and assistant linebackers coach for the Minnesota Vikings. Rallis went into coaching following a playing career at the University of Minnesota, getting his start as a quality control coach at Wake Forest.

He will be tasked with improving a Cardinals defense that was 22nd in the NFL by yards per play allowed in 2022 as Arizona slumped to a 4-13 record.

Arizona tight end Maxx Williams was college team-mates with Rallis. He wrote on Twitter: "So pumped to see this!!!"

On Sunday, it was reported the Cardinals have also hired their offensive coordinator, appointing Drew Petzing to the role. Petzing was previously the quarterbacks coach for the Cleveland Browns, having held the same position with the Vikings, for whom he worked with Gannon.
