FOXBORO, Mass. — The New England Patriots could go into their Week 11 matchup with the Buffalo Bills dangerously shallow at cornerback.

Justin Coleman has missed three consecutive practices with a hand injury, leaving just three healthy cornerbacks on the roster. Malcolm Butler and Logan Ryan will start Monday, and as of now, Rashaan Melvin would be the No. 3 player at the position.

The Patriots could sign Chris Greenwood or Brock Vereen off their practice squad before Monday night, or they could move Devin McCourty or Patrick Chung to cornerback in an emergency.

Check out the Patriots’ full injury report from Friday:

CB Justin Coleman (hand)
LB Jamie Collins (knee)
WR Julian Edelman (foot)

DT Alan Branch (elbow)
OT Marcus Cannon (toe)
Guard Tre’ Jackson (knee)
DE Chandler Jones (abdomen)
WR Keshawn Martin (hamstring)
Guard Shaq Mason (knee)
DE Jabaal Sheard (ankle)
OT Sebastian Vollmer (concussion)
