KANSAS CITY, Mo. — The Kansas City Chiefs have hired Tom McMahon to coach special teams while cutting ties with three assistants from former head coach Todd Haley's staff.

McMahon will take over for Steve Hoffman, who was not retained after Romeo Crennel was elevated from interim head coach to the permanent job. Also let go were wide receivers coach Richie Anderson and assistant offensive line coach Pat Perles.

The team announced the moves Monday.

McMahon has spent the past three seasons coaching special teams for St. Louis. He's also spent time with the Atlanta Falcons and in the college ranks with Louisville.

The Chiefs still have not decided on an offensive coordinator.
