BUFFALO, N.Y. — The NFL is getting another Gronk.

The Buffalo Bills agreed to a deal Saturday with Glenn Gronkowski, a fullback from Kansas State who went undrafted and is the brother of Patriots star tight end Rob Gronkowski.

Gronkowski tweeted after the draft ended Saturday: “staying home. Go bills!”

Two officials familiar with the deal confirmed it to The Associated Press on Saturday night, speaking on condition of anonymity because the team has not announced the move.

The Gronkowskis are from suburban Buffalo, where their father Gord owns a gym.

Glenn would be the fourth Gronkowski brother with NFL experience. Besides Rob, Chris and Dan also played professionally.

Glenn Gronkowski, at 6-foot-2 and 239 pounds, had 16 rushes for 51 yards and a touchdown at Kansas State in three seasons.
