The Buffalo Bills stormed into their fourth straight playoffs on the back of a Tyler Bass field goal as time expired which edged them past the Miami Dolphins 32-29 in snowy conditions on Saturday.

Bass converted his 25-yard attempt for his fourth career fourth-quarter or overtime field goal to clinch victory with scores locked amid a wild contest at Bills Stadium where the Dolphins had rallied from a 21-13 half-time deficit to lead 29-21 in the last.

Bills quarterback Josh Allen was heroic, going on a dazzling 44-yard run, the second longest of his career, before capping the same drive with a TD pass for Dawson Knox to make it 29-27 as the snow started to fall heavily in the fourth quarter.

Allen then took the airborne route to convert the two-point conversion to square up the game, breaking the plane of the goal line by inches on review after it had originally been ruled short.

The 26-year-old QB finished the game with four touchdown passes, completing 25 of 40 attempts for 304 yards, with 77 rushing yards on 10 carries.

Allen linked up with Quinton Morris, Nyheim Hines, James Cook and Knox for TD passes, showcasing his elite composure to find Cook right on half-time to open up an eight-point lead. 

The Bills' efficiency was arguably the difference in a gripping AFC East contest, with Miami settling for two field goals and one TD from Salvon Ahmed in the first half.

The Dolphins sparked to life in the third with Tua Tagovoiloa linking up with Jaylen Waddle on a 67-yard TD pass, before finding Tyreek Hill for another score to claim a 26-21 lead. 

Tagovailoa completed 17 of 30 passes for two touchdowns with no interceptions, as Miami slipped to their third straight loss and an 8-6 record, behind the Bills (11-3) in the AFC East.
