As Brian Burns spoke at his locker after the Giants’ 20-15 loss to the Cowboys, he shouted across the room to Malik Nabers. “You good?” Burns asked the rookie wide receiver. “You straight?” Nabers shook his head no. Nabers exited with a concussion late in the fourth quarter of Thursday night’s prime-time game at MetLife Stadium. His head struck the turf as he attempted to haul in a 4th & 6 pass from Daniel Jones near the sideline with 3:30 remaining. The pass fell incomplete, and Nabers remained down for a while before going into the medical tent and, ultimately, back into the locker room. The 21-year-old did not address the media, as he is now in concussion protocol, but he spoke at his locker with teammates including Jones and Jalin Hyatt. In a post to his Instagram story later in the night, Nabers wrote, “All good. Thanks for all the prayers!!!” The injury brought a sudden end to the latest electric performance by the rookie. “He took some big shots today,” left guard Jon Runyan said. “That was tough. In real time, I thought that he caught it. I was really pumped for him. He left it all out there.” Nabers finished with 12 catches for 115 yards. His 35 receptions this season are the second most in a player’s first four games in NFL history, trailing only the 39 recorded by the Rams’ Puka Nacua last year. Nacua went on to set the records for receptions (105) and receiving yards (1,486) in a rookie season. Nabers, whom the Giants drafted out of LSU with the No. 6 pick in April, now boasts 386 yards and three touchdowns. He got 15 targets Thursday — his third consecutive game with at least 12. “He’s doing some good things,” head coach Brian Daboll said before going to check in with Nabers. “Glad we have him. … Now I’m going to see him here. I hope he’s OK.” Playing in prime-time for the first time as a pro, Nabers needed only three offensive snaps Thursday to make his mark. With the Giants facing 3rd & 4 on their opening possession, Nabers used a nasty double move to blow past Cowboys cornerback Andrew Booth. The wide receiver faked a step inside, then surged upfield as Booth twisted toward the MetLife Stadium turf and used his left hand to catch his balance. A wide-open Nabers collected a 39-yard reception from Jones for the longest catch of his red-hot rookie season. That drive ended with a 52-yard field goal by Greg Joseph, giving the Giants an early 3-0 lead. “He played a heck of a game again and he showed up for us big time,” Jones said, “so we’ll keep trusting him with it.” Nabers’ exit occurred one play after Cowboys star pass rusher Micah Parson left with an ankle injury. Thursday’s divisional showdown commanded extra attention after a comment made by Nabers during the offseason drew the ire of Trevon Diggs, the Cowboys’ top cornerback. Asked which NFL cornerback he couldn’t wait to line up against, Nabers replied, “Trevon Diggs.” In a not-so-subtle retort, Diggs wrote on X, “Giants been getting belt for some years now.” “I mean, it is what it is, but I don’t really wanna talk about it,” Nabers said this week in reference to that controversy. “I mean, it’s game time now.” The ball-hawking Diggs doesn’t normally travel with an opponent’s top receiver, but — with fellow cornerbacks DaRon Bland and Caelen Carson out with injuries — he frequently lined up across from Nabers. Most of Nabers’ success came on plays he wasn’t guarded by Diggs, though he hauled in a seven-yard reception on 4th & 3 on a fourth-quarter drive that ended with Joseph’s fifth field goal of the night. Nearly a decade earlier, another superstar receiver from LSU, Odell Beckham Jr., introduced himself to the national audience with his one-handed touchdown catch against the Cowboys at MetLife Stadium on “Sunday Night Football” on Nov. 23, 2014. That was Beckham’s seventh career game. In a bit of foreshadowing, Michael Strahan shared during Amazon Prime Video’s pregame coverage Thursday that Giants co-owner John Mara told him during training camp that Nabers had the “best skill set and best body control” the team had seen since Beckham. And while Nabers didn’t deliver any highlights approaching the degree of difficulty of Beckham’s instant-classic catch — unlike Sunday, when he ripped one ball away from a Browns defender and later hauled in a twisting touchdown grab — he once again lived up to the sky-high hype. “Injuries are always tough, but we know he’s fighting hard,” left tackle Andrew Thomas said. “Whenever he’s healthy, we’re excited to have him back.” Nabers would need to be cleared within the next 10 days to play in the Giants’ next game on Oct. 6 in Seattle.
