The Jets’ young receiving corps just got even thinner.

Quincy Enunwa suffered a non-contact neck injury during 7-on-7 drills before Saturday night’s Green and White scrimmage at MetLife Stadium. The severity of the injury was not immediately known and it’s unclear how long he could be sidelined.

Enunwa, 25, the position group’s best and most experienced weapon, was injured while running a slant route in front of the end zone. Before anyone knew it, even the quarterback who threw the ball, Enunwa dropped the ball and fell to the turf. Trainers tended to him on the field before escorting him to the locker room.

“I didn’t see much,” said Christian Hackenberg, who was in at quarterback on that 7-on-7 drill. “I threw the ball and I turned around to get the next play and then he was down. Quincy’s a great guy. He’s one of the guys I look up to on the team. He’s a hard worker, does everything the right way, so I’m hoping everything works out. He’s a tough kid, so he’ll do everything he can to get back on the field.”

Quarterback Bryce Petty said: “The way he was walking back was kind of weird when he went down. So unfortunate because Quincy had a great camp, you know. Hopefully, everything is OK and he will be back for us.”

According to coach Todd Bowles, Enunwa suffered the same injury previously. “Something went wrong when he fell,” he said. “[The trainers] said it was the same thing he had in the spring. It wasn’t severe, but it held him out a little while. I’ll see the severity when I go inside.”

Enunwa caught 58 passes for 857 yards and four touchdowns last season. After the offseason departures of Brandon Marshall and Eric Decker, Enunwa assumed a leadership role among the Jets’ young receivers. Now there’s a chance they, and the rest of the offense, could be without him for some time.

“We’ll see what happens first. If we have to lose him, we’ll adjust from there,” Bowles said. “But we’ve got some young guys coming on, so we’ll see what the results are first and we’ll go from there.”
