Barmore (shoulder) did not participate in Wednesday's practice.
Barmore sustained a shoulder injury during the Patriots' 35-6 loss to the Jaguars in Week 3, finishing with only two tackles (one solo) while playing a season-low 28 defensive snaps. He'll have two more chances to return to practice ahead of Sunday's game against the Bills. If Barmore is not cleared to play, then Joshua Farmer and Jeremiah Pharms would both be in line for larger roles against Buffalo.
