The Patriots have announced three roster moves: DT Vince Wilfork has been placed on season-ending injured reserve, WR Austin Collie has been signed, and TE Zach Sudfeld has been waived.
Two of those moves were expected. The third, with Sudfeld was not. But the rookie has failed to play in the regular season as well as he did in the preseason, and combined with a hamstring injury suffered in the opener against Buffalo, he has played just 45 total snaps over three games, including eight in Atlanta, where he muffed a Falcons' onside kick.
If he clears waivers, Sudfeld can be brought back to the Patriots' practice squad; the assumption is the team will promote a player off practice squad for Sunday's game to fill the now-open roster spot.
Wilfork's season is officially over; the team used its one IR-designated to return exception on Shane Vereen, though given Wilfork had Achilles surgery, it was highly unlikely he would have been physically ready to return this season, even for the playoffs.
Collie, 27, was a fourth-round pick of the Colts in 2009. He spent some time with the 49ers in training camp this year, but has suffered three documented concussions in his career and suffered a knee injury last year, both of which have derailed a once-promising career.
