Shepard (quadriceps) was listed as a limited participant on Wednesday's estimated injury report, Dan Salomone of the Giants' official site reports.
Shepard earned a limited listing on the Giants' last two Week 13 reports, but he was considered doubtful to play and eventually was inactive this past Sunday at Miami. Among New York's top three wide receivers, Shepard was the only one to fit in some reps Wednesday, as both Kenny Golladay (ribs) and Kadarius Toney (oblique/quadriceps) didn't participate. Consequently, if Shepard puts himself into a position to suit up this weekend against the Chargers, he could serve as the team's No. 1 receiver, though he may be working with either Jake Fromm or Mike Glennon (concussion) as his quarterback with Daniel Jones (neck) having yet to receive clearance for contact.
