FOXBORO, Mass. — In a series of moves, the Patriots announced a surprising roster transaction.

Zach Sudfeld was released by New England on Thursday afternoon as the team announced it has signed Austin Collie and placed Vince Wilfork on injured reserve.

The undrafted tight end was a star during the summer in OTAs and training camp. He struggled during the preseason and regular season. He was targeted twice during the season but did not record a reception.

Sudfeld’s release could be a good sign for Rob Gronkowski‘s return. The move leaves just Gronkowski, Matthew Mulligan and Michael Hoomanawanui on the roster.

If Sudfeld clears waivers, he could return to the team’s practice squad.
