Six of the seven, including Cox, were cut by the Giants on Saturday before rejoining the team on Sunday. They include cornerbacks Bennett Jackson and Chandler Fenner, linebacker Dan Fox, defensive end Jordan Stanton, and wide receiver Julian Talley.
Cox was the Giants' seventh-round draft pick last year. He played in 14 games as a rookie, including one start. He also led the team with 20 kickoff returns for 436 yards.
The seventh player signed to the Giants practice squad was offensive tackle Nick Becton, who was waived by San Diego. He signed with the Chargers as an undrafted free agent last year and spent most of his rookie season on San Diego's practice squad, although he was on the active roster for six weeks and appeared in one game.
