The Kansas City Chiefs knocked the Bills out of the play-offs in four of the past five years but with the Chiefs missing out this season, along with AFC rivals Baltimore and Cincinnati, this was meant to be Buffalo’s year.<\/p>\n
Despite being the AFC’s sixth seed, Buffalo were still narrow favourites against a team that had won 13 of their previous 14 games and a defence that led the league for sacks – yet it was turnovers that hurt the Bills.<\/p>\n
Allen had not turned the ball over in any of his six previous play-off games but had two fumbles in three plays either side of half-time, both resulting in Denver field goals.<\/p>\n
That added to the Broncos’ lead after touchdowns by Frank Crum and Lil’Jordan Humphrey cancelled out Mecole Hardman’s opener for Buffalo.<\/p>\n
Allen had also thrown 200 passes without an interception before being picked off in the third quarter here, yet the 29-year-old regrouped to help Buffalo put up 17 unanswered points thanks to Keon Coleman and Dalton Kincaid touchdowns in the fourth quarter.<\/p>\n
After a Marvin Mims score put Denver back in front with 55 seconds left, Allen led the Bills into position for 41-year-old Matt Prater to level matters with a last-gasp field goal <\/p>\n
However, even though the Buffalo defence got a stop on the first possession of overtime, Allen gave up his fifth turnover of the day as Denver cornerback Ja’Quan McMillian claimed an interception in a contested catch with Brandin Cooks.<\/p>\n
Wil Lutz’s fourth field goal ensured Allen has lost all three of his overtime games in the post-season, and all seven overall in his career.<\/p>\n
Allen and boss Sean McDermott also have the most play-off wins by a quarterback and head coach without reaching a Super Bowl (eight).<\/p>\n
