Coughlin is expected to miss "months" after sustaining a pectoral injury during Sunday's 28-6 loss to the Vikings, Ralph Vacchiano of Fox Sports reports.
Coughlin played 10 special-teams snaps and failed to record a stat before leaving Sunday's contest with what appears to be a serious pectoral injury. The Giants are losing one of, if not their most impactful special-teams asset for the foreseeable future, and Ty Summers is expected to see more special-teams work in Coughlin's stead.
