K-State fullback Glenn Gronkowski gets deal with Buffalo Bills

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!” The Gronkowskis are from suburban Buffalo.

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