[Kansas City.com] Bill Muir, the offensive coordinator for the Chiefs last season, told the team this morning that he is retiring.

The Chiefs are looking for a new offensive coordinator but had asked Muir to return as their offensive line coach. Muir has served as offensive line coach since joining the Chiefs in 2009.

“I feel badly because they want me to stay,” said Muir, 69. “I’m not leaving because of anything that has gone on or is going on or will go on with the Chiefs. This is a personal decision. It’s very personal. I’ve been denying myself a lot of things over the years but I’m at a point in my life where I want to do some other things.”

Quarterbacks coach Jim Zorn has interviewed for the vacant coordinator’s position.
