Snee will spend the night in a local hospital under observation for the concussion according to the team.
Snee, a Pro Bowl guard, is the team's best offensive lineman. It remains to be seen if Snee will be able to play against the Bills next Sunday.
The Giants already were without starting center David Baas, who sat out the game with a burner/neck injury.
