New England Patriots tight end Rob Gronkowski has been a touchdown machine in 2015, and it continued in Week 2 against the Buffalo Bills.

In the second quarter of Sunday's game, Gronkowski caught another touchdown pass, this one of the 2-yard variety. It was his eighth consecutive game -- including the playoffs -- with a touchdown reception, which is the longest active streak in the NFL.

The touchdown helped the Patriots get out to a 21-7 lead against the Bills as the two teams battle for first place in the AFC East.
