Shepard was added to the injury report Friday with a calf injury and is listed as questionable for Sunday's game against Dallas, Art Stapleton of The Bergen Record reports.
The late-week addition is cause for concern, even with the Giants listing Shepard as a limited participant on their Friday practice estimate (the session was just a walk-through). The veteran wide receiver caught two of four targets for 27 yards in last week's loss to the Chargers, playing 81 percent of snaps on offense in his first game back from a five-week absence caused by a quad injury. Shepard also missed time with a hamstring strain earlier this year, with lower-body injuries a recurring theme for him the past three years. An absence this Sunday could leave Pharoh Cooper as the Giants' slot receiver, with Colin Johnson also a candidate to take on snaps alongside Kenny Golladay and Darius Slayton.
