Slayton -- who isn't practicing Wednesday -- has a neck injury rather than an arm injury, Ryan Dunleavy of the New York Post reports.
Slayton was ruled out of this past Sunday's win over Washington with what was described as an arm injury after taking a big hit shortly before halftime. The Giants have since classified Slayton's injury differently, but his status will be worth monitoring heading into this Sunday's matchup with New England nonetheless. He will have two more opportunities to practice this week before the Giants potentially give him an injury designation.
