[Kansas City.com] Chan Gailey has been relieved of his duties as Chiefs offensive coordinator, although it was unclear Monday morning whether he would remain with the team in some other capacity.

Coach Todd Haley, who was the Arizona Cardinals’ offensive coordinator before coming to the Chiefs, appeared unhappy with the play-calling Saturday night in the Chiefs’ 14-10 loss to the Seattle Seahawks at Arrowhead Stadium. At Monday morning’s practice, Haley was directing the offense, while Gailey was nowhere to be seen.

The Chiefs have just two offensive touchdowns so far, and they certainly weren’t helped when quarterback Matt Cassel was injured Saturday night. Cassel has gone down four times despite attempting only 19 throws. He was hurt when he was sacked on his first pass attempt against the Seahawks, and it’s possible he might be out for up to four weeks with a strained knee. The Chiefs were expected to address his status today.
