The Chiefs have hired Brian Daboll as their new offensive coordinator, according to reports by ESPN and NFL Network.

Bill Muir, who had been the Chiefs' O-coordinator, announced his retirement Wednesday.

Daboll served in the same capacity with the Dolphins last season under Tony Sparano, following two seasons in Cleveland as the Browns' OC. He also had worked with new Chiefs head coach Romeo Crennel and Chiefs GM Scott Pioli when all three men were in the Patriots' organization from 2000 through 2004.

According to ESPN, other candidates under consideration for the Chiefs' OC job were QB coach Jim Zorn and former Raiders OC Al Saunders. Earlier in the week, the Bears had sought permission to interview Zorn for their vacant QB coach job, but the Chiefs denied their request.
