Head coach Ben McAdoo confirmed Monday that Vereen has entered the concussion protocol, Ralph Vacchiano of SNY reports.
In his first game back from missing nine due to a triceps injury, Vereen logged just three snaps before sustaining a concussion. With their pass-catching running back potentially out of the picture in the short term, the Giants will rely upon Rashad Jennings and rookie Paul Perkins to fuel the rushing attack.
