Pendergast was the defensive coordinator last season coming from the Arizona Cardinals with Todd Haley.
Romeo Crennel was hired to coach the defense earlier this month lending plenty of speculation that Pendergast was on his way out. Haley indicated at the press conference introducing Crennel that the decision to stay or go would be up to Pendergast.
Teicher reports the decision for Pendergast to leave was "mutual" between the two sides.
Also out is Dedric Ward, who Teicher reports has been fired.
Ward was the receivers coach for the Chiefs before being demoted in October.
Richie Anderson will continue to fulfill his role as the Chiefs receivers coach.
Potential landing spots for Pendergast are unclear at the moment. He's been "relieved of his duties" from his last two defensive coordinator stints in as many years so I would be a bit surprised if he was anything more than a position coach in 2010.
However, Chan Gailey has hired multiple former Chiefs assistants in Buffalo and has also hinted at potentially running a 3-4 defense. Gailey and Pendergast worked together with the Dallas Cowboys.
With the departure of Bob Bicknell, that makes three coaches off the staff this week.
As always, we wish the best of luck to all of them in the future.
