Robinson, a starting cornerback, returned to the lineup on Sunday after missing two games following an emergency appendectomy. While trying to defend a run play, Robinson appeared to slip and get his leg twisted under a block attempt by Chicago fullback Khari Blasingame.
So far this season Robinson has six tackles and a pass defensed in 72 defensive snaps over two games. The 2021 third-round pick must now sit out at least four games.
The Giants are thin at cornerback.
Rookie third-round pick Cor’Dale Flott missed Sunday’s game with a calf injury. Reserve cornerback Nick McCloud has been out since Week 1 with a hamstring injury.
Fabian Moreau, a veteran cornerback initially signed to the practice squad, is now on the 53-man roster and is the starter opposite Adoree’ Jackson. Darnay Holmes is the team’s slot cornerback. The only healthy backup on the 53-man roster currently is Justin Layne, a fourth-year player who has yet to play a defensive snap this season.
The Giants have two cornerbacks on their practice squad. They are rookie Zyon Gilbert, an undrafted free agent, and Ojaijah Griffin, a former undrafted player who spent the 2021 season on the Buffalo Bills’ practice squad.
A corresponding roster move has not been announced.
