Cardinals coach Steve Wilks has been relieved of his duties, the team announced Monday.
The news was first reported by NFL Network's Ian Rapoport.
Arizona also fired offensive coordinator Byron Leftwich and defensive coordinator Al Holcomb, per ESPN's Josh Weinfuss.
Wilks is the first head coach to get fired after one season since Chip Kelly's lone season with the San Francisco 49ers in 2016. Wilks replaced Bruce Arians as head coach in January.
Wilks, 49, finished his first season as an NFL head coach. He previously served as an assistant with the Carolina Panthers under Ron Rivera, San Diego Chargers with Norv Turner and Chicago Bears alongside Lovie Smith.
Former Green Bay Packers head coach Mike McCarthy has reportedly expressed interest in the vacancy.
The Cardinals finished the year at 3–13 with a 27–24 loss to the Seahawks on Sunday.
