Glenn Gronkowski, brother of Rob, signs with Bills as UDFA

"Baby Gronk" is staying close to home as he begins his NFL career.

Former Kansas State fullback Glenn Gronkowski, the youngest brother of New England Patriots tight end Rob Gronkowski, is signing with the Buffalo Bills as a free agent after going undrafted.

The Gronkowskis are from the Buffalo area, so it's a natural fit.

The Bills and Patriots are of course, rivals, but it's unlikely the Gronkowski brothers will meet on the field because both line up on the offensive side of the ball.
