The injury will end his season and perhaps his time with the Giants. Shepard, the longest-tenured player on the team, is in the final year of a restructured deal he signed this offseason off a torn left Achilles.
"He's a tremendous person. He's worked so diligently to get back," Daboll said. "Feel so terrible for him that he's had that injury. Big part of our team. Going to miss him out on that field."
The noncontact injury happened in the final minutes of New York's 23-16 loss to Dallas. It came on a seemingly innocuous play where Shepard was simply jogging near the right sideline when he crumbled to the ground.
"I'm thinking the same thing as you watch it. He's just slowing down," Daboll said. "It could have happened, I'm not saying it happened, but you see a couple plays before where he kind of turns when he's running an in-cut and he's extended. But he went out there on the next play and did something. Again, kind of looked like a freaky accident there."
This latest odd injury to Shepard only exacerbates the turf vs. grass debate.
"I know there have been a lot of studies. Not just here but probably in every stadium," Daboll said on Tuesday. "I think, again, you look at Shep's injury, he was jogging. I'm sure throughout the season and the offseason we'll sit down and discuss those types of things."
The turf at MetLife Stadium in particular has been the subject of some complaints in the past, including by the San Francisco 49ers after five players suffered game-ending lower-body injuries in the same game against the New York Jets during the 2020 season. The knee injuries suffered by Nick Bosa and Solomon Thomas were season-ending.
"Everybody in this league should do everything they can to put the best surface out there. How much is invested in the players who go out there and play, and our league really is a player-driven league, and we want those guys to have the best of the best, especially surfaces to play on," coach John Harbaugh said.
Harbaugh added about the MetLife field surface: "That turf was matted down, it was packed down, it was a little tight. Maybe that's how it's supposed to be. I don't know, but that's what I saw. It was a little tough."
The Ravens will play again at MetLife Stadium this season in Week 6 when they face the Giants.
The injury had Shepard's close friend and former teammate Odell Beckham Jr. expressing his disgust with stadiums using turf over grass.
"Billions made off this game I can't understand why we can't play on grass," he tweeted, also offering prayers for Shepard.
Shepard was cleared to practice late this summer after tearing his left Achilles last December. He leads the Giants with 154 receiving yards through three games. He has also played the most snaps (157) of all the team's receivers.
The injury occurred on the Giants' final offensive play Monday night. The result of the play was essentially a game-ending interception by Dallas' Trevon Diggs. Shepard limped onto the cart and players from both teams came over to offer words of encouragement.
The Giants (2-1) move forward now hoping to get either Toney or Robinson back this week. Both missed Monday night's game because of injury. Robinson, the Giants' second-round pick in the 2022 draft out of Kentucky, was injured in the opener against the Tennessee Titans. Toney, their first-round pick in 2021 out of Florida, recently aggravated the hamstring that plagued him this summer.
"They're getting closer. Will they be ready this week [vs. Chicago]? I can't answer that yet," Daboll said. "From the meetings I just had with the doctors, they're getting closer. But we're not out of the blue yet with it."
Golladay is the Giants' second-highest paid player this season at $18 million. But he can barely get on the field. He played just two snaps last week in a win over the Carolina Panthers. He had no catches on three official targets with a drop in 22 snaps against the Cowboys.
Golladay made it clear last week that he wasn't happy with the Giants' decision to sit him behind David Sills V. Shepard's injury and Sills' struggles (he fell on the play where Shepard was hurt that led to the interception) could create more playing time for Golladay.
New York is trying to get more out of their $72 million man.
"The same thing we try to do with all our guys. We go out there, install the game plan with them and work as hard as we can work. Build trust with the quarterback," Daboll said. "When he has opportunities to go out there and make plays, he goes out and makes them."
Golladay can only hope to have some of the success that Shepard did in New York. Shepard has 362 career catches for 4,038 yards and 22 touchdowns in his Giants career. Golladay has yet to score a touchdown in 17 games since signing the massive deal. He has two catches for 22 yards this season.
Shepard's problem in recent years hasn't been his production. It has been his health.
This will be the fourth straight year he has missed at least four games because of injuries. He has dealt with Achilles, quad, hamstring, toe and concussion problems the past few years. Now, it's his knee.
Shepard posted Wednesday on Instagram to express his gratitude at the support he has received from family, friends and fans.
Shepard was able to get back from the Achilles injury in just over eight months. He looked good at practice late this summer and returned to game action for the season opener against Tennessee on Sept. 11. He caught a 65-yard touchdown in that contest.
That, unfortunately, will remain the highlight of his 2022 season.
