The Giants placed quarterback Daniel Jones (neck) and wide receiver Sterling Shepard (Achilles) on injured reserve and filled the two spots on the roster by signing linebacker Jaylon Smith and cornerback Jarren Williams.
Smith — signed to the practice squad Friday and the roster Saturday — played 17 snaps and was credited with four tackles (three solo) in his Giants debut.
"Jaylon … had about four to six hours of coaching to get him ready for the game and a walk-through with the defense," coach Joe Judge said. "I really liked the way this guy responded, and he's been a pleasure to coach in the short window we've had. He went out there, he played fast, he's able to go ahead and get his hat on a few people to make some plays."
Williams made his first NFL start and played all but one snap because cornerbacks Adoree' Jackson and Aaron Robinson are on the Reserve/COVID-19 list. He finished with five tackles (four solo) and a pass defensed.
"Jarren's a guy that's been doing a decent job for us playing defense, some roles in the kicking game," Judge said. "I think he's a guy that's got a future that we can go ahead and keep on developing with. I like the way Jarren works, and I think there's some upside with him as a player. He definitely has the right attitude as a person."
The Giants placed another cornerback, Keion Crossen, on the COVID-19 reserve list. He joins wide receivers Kadarius Toney and John Ross, linebackers Cam Brown and Oshane Ximines, safeties Xavier McKinney and J.R. Reed, Jackson, Robinson, and practice squad corner Natrell Jamerson on the list.
"Not having Keion, obviously that's a player we want to have for his roles in the kicking game and also on defense for depth," Judge said. "The guys who are available to us, we'll know more through tomorrow and we'll plan accordingly. There's an opportunity for some guys to come off the COVID list before the game and we'll see what that's going to entail in terms of the ramp-up period and whether or not they'll be available. They'll have a realistic chance to go out there and play for us, we'll get everyone prepared whether it's in person or through zoom, make sure we monitor everybody's health, make sure number one that they're healthy and number two, when we put them on the field, we can assure thing, go out there and make them function, operate and be safe."
