The Patriots are already thin at tight end, but they might be even thinner come Thursday night.

Undrafted rookie tight end Zach Sudfeld pulled a hamstring during the Patriots’ win in Buffalo on Sunday, according to Ben Volin of The Boston Globe.

Sudfeld didn’t catch a pass and was targeted just once, a pass that resulted in Tom Brady‘s only interception, in the game. He played sparingly in the second half with veteran Michael Hoomanawanui and tackle Nate Solder getting most of the reps at tight end, which might be because of the injury.

With Rob Gronkowski still working his way back from offseason surgeries and unlikely to play again this week, the Patriots could not afford to lose either Sudfeld or Hooman right now. With Gronk and Sudfeld now both uncertain for Thursday night’s game against the Jets, though, the Patriots are left with Hooman as the only healthy tight end on the roster. Fullback James Develin could fill in at the position in case of emergency, but it’s likely the Patriots will sign another tight end to the active roster — maybe Daniel Fells or Matthew Mulligan — ahead of Thursday’s game.
