Though Gray remains of the Patriots' practice squad, he is a candidate to be promoted to the team's active roster in the wake of Stevan Ridley's season-ending injury, csnne.com reports. If Gray is promoted, he would add depth to a backfield that still rosters Shane Vereen, Brandon Bolden and James White, though in such a scenario the 5-10 230-pounder could carve out a role in the Patriots' backfield down the road.
