Harris was claimed off waivers by the Giants on Tuesday, Paul Schwartz of the New York Post reports.
Harris, who was waived by the Chargers on Monday, will provide the Giants with extra depth at linebacker, though his main vocation will be on special teams.
Shepard (ankle) said he went full speed at Wednesday's practice and felt good afterward, Jordan Raanan of ESPN.com reports.
Listed as a limited participant Wednesday, Shepard put himself on track to record a full session by the end of the week. Giants head coach Ben McAddo agreed that the wideout looked good at practice, albeit while limited to individual work. Shepard has two more chances to practice fully with his teammates before the Giants face the Seahawks on Sunday. He'll likely be highly targeted once he's able to play, considering the Giants won't have Odell Beckham (ankle) or Brandon Marshall (ankle) for the rest of the season. Shepard did admit after Wednesday's practice that he still isn't sure about returning for Week 7, Art Stapleton of The Bergen Record reports.
Perkins (ribs) was limited at Wednesday's practice.
In his first practice since bruising his ribs in Week 4, Perkins managed to take part in individual drills, at the very least. The Giants will likely take a cautious approach with Perkins due to the emergence of Orleans Darkwa, who has racked up 29 carries for 186 yards and one touchdown during the former's two-game absence. Once healthy, it's unclear if Perkins will regain any type of significant role.
Shepard (ankle) was limited in practice Wednesday.
Shepard is working his way through his second left-ankle sprain in three months, the first of which sidelined him for nearly two weeks. On this occasion, he greeted Day 10 with individual drills and running without a limp, according to Ralph Vacchiano of SportsNet New York. Expect Shepard's status for Sunday's game against the Seahawks to receive clarification by the time Friday's injury report is released.
Harrison recorded his first sack of the season in Sunday night's win over the Broncos.
Harrison added four tackles (three solo) to go along with his take down of the quarterback. The 28-year-old defensive tackle was on the field for just 32 defensive snaps (40.0 percent).
