Bills preparing to move on from Rex Ryan as head coach

— -- As Buffalo?tries to prevent Cleveland?from winning its first game of the season on Sunday, Rex Ryan is probably coaching his final games as the Bills' head coach, according to league sources.

Ryan is aware of what's ahead, sources said, which creates an awkward situation surrounding the Bills until the change is made.

While Buffalo is preparing to move on from Ryan, the organization is expected to retain its general manager Doug Whaley, who is expected to be given a chance to hire his third different head coach, after having a hand in the hirings of Ryan and former Bills head coach Doug Marrone. But the cycle of change in Buffalo is expected to continue.

The Bills (6-7) have lost two straight and five of their past seven and have not made the playoffs since 1999 -- the longest active postseason drought in the NFL.

Ryan, in the second year of a five-year deal, is on his second head-coaching job after being fired by the New York Jets following the 2014 season.
