Sean McDermott led the Bills to 98 NFL regular season wins
The Buffalo Bills have sacked coach Sean McDermott after a play-off defeat by the Denver Broncos.
McDermott, 51, was the Bills' coach for nine seasons but despite having star quarterback Josh Allen and winning the AFC East on five occasions was unable to reach a Super Bowl.
Allen had a chance to clinch victory in overtime at the weekend but his fourth turnover of Saturday's Divisional Round game allowed the Broncos to kick a field goal and win 33-30.
"Sean helped change the mindset of this organisation and was instrumental in the Bills becoming a perennial play-off team," said owner Terry Pegula
