No decision has been made about the future of general manager Scott Pioli.
Crennel was fired Monday after one full season as coach, and one day after Kansas City lost 38-3 to the Denver Broncos to match the fewest wins in franchise history.
The Chiefs' only victories came against New Orleans and Carolina, the latter coming one day after linebacker Jovan Belcher shot his girlfriend to death and then drove to the team's practice facility and turned the gun on himself as Crennel and Pioli looked on.
Crennel's career record is 28-55 in five-plus seasons as a head coach.
