McKelvin fielded the ball at the 21-yard line, following a Miami three-and-out on the opening possession. He then ran it back 79 yards for the score. That put the Bills up 7-0, and the offense added a field goal later in the first quarter to jump out to a 10-0 lead over their visiting AFC East rival.
McKelvin's first punt-return touchdown this season was an 88-yard score against the Kansas City Chiefs. Together, those punt-return touchdowns are two of the three longest in the NFL this season.
Miami used its special teams to do what the offense has been unable to do so far -- score a touchdown. Marcus Thigpen took the ball 94 yards down the field to put the Dolphins on the board, making it a 10-7 game. Thigpen's score was the first Dolphins kick-return touchdown in three years.
