Watch: Josh Allen scores TD on electrifying 52-yard run

Up 14-0 on a third-and-8 from near midfield, Allen dropped back to throw, but the Steelers' pass-rush forced him to tuck the ball and run.

Allen easily picked up the first down, broke through an arm-tackle attempt and accelerated past the defense and into the end zone.

According to NFL Next Gen Stats, Allen hit a top speed of 19.33 miles per hour, his fastest in 2023. He also gained the most yards on a scramble and the most rush yards over expected by a quarterback this season.

Per StatHead, it was the longest rushing touchdown run of Allen's career. The score gave Buffalo a commanding 21-0 lead over a Steelers team that averaged 17.9 points per game during the regular season.

On top of his electrifying run, Allen is carving up the Steelers through the air. At the half, he's 15-of-21 for 146 yards and two touchdowns.

With a win, the Bills will host the Chiefs next Sunday in the AFC divisional round.
