Scott Pioli is out as general manager of the Kansas City Chiefs after four years.
A team statement said the two sides ''mutually parted ways.''
The NFL club had already dismissed coach Romeo Crennel earlier this week following a 2-14 season, and Chiefs chairman Clark Hunt said then additional changes could be made.
Pioli was hired from the New England Patriots in January 2009 and quickly fired coach Herm Edwards.
Pioli turned to Arizona Cardinals offensive coordinator Todd Haley as head coach and made his first major player move that offseason by acquiring quarterback Matt Cassel from the Patriots following his strong performance in place of the injured Tom Brady.
In 2010, the Chiefs won their first AFC West title since 2003. But a poor start the following season cost Haley his job late in 2011, with Crennel promoted from defensive coordinator.
