Chiefs' Muir retires after 34 years

THE ASSOCIATED PRESS

KANSAS CITY, Mo. -- Offensive co-ordinator Bill Muir informed the Chiefs on Wednesday that he will retire after 34 years in the NFL, a move many had expected after Kansas City struggled much of last season.

Muir joined the Chiefs as offensive line coach in 2009 and was elevated to offensive co-ordinator by then-coach Todd Haley, who was fired midway through this season.

The longtime assistant also spent seven seasons in Tampa Bay, where he won a Super Bowl as part of Jon Gruden's staff. The Buccaneers won three division titles during his time there.

Muir was not expected to remain the Chiefs' offensive co-ordinator even if he remained on staff. New coach Romeo Crennel has said he hopes to have that position filled sometime after the Super Bowl.
