After an incomplete pass on first down, quarterback Josh Allen handed off to running back Devin Singletary. With the help of a big hole from the offensive line, Singletary burst up the field for a 46-yard touchdown. The run was the second-longest of his career, behind a 51-yard touchdown run against the Denver Broncos last season.
It is the longest rushing touchdown the Dolphins have allowed in more than five seasons. The last time Miami allowed a 40-plus yard rushing TD was in Week 14 of the 2016 season against the Arizona Cardinals -- a 56-yard run by J.J. Nelson.
Singletary reached a top speed of 20.29 mph on the touchdown run, per NFL NextGen Stats. It is the fastest speed he has reached on a play of his career.
The Bills took a 7-0 lead with the score and added a touchdown pass from Allen to Stefon Diggs on their second possession, extending their lead to 14-0.
