Enunwa injured his neck Saturday night during practice at MetLife Stadium, an injury that coach Todd Bowles said was similar to the one that held the receiver out during spring workouts.
Enunwa dropped a pass from Christian Hackenberg during 7-on-7 drills when he took a step and fell to the turf face-first despite being untouched.
“He hit his head or hit his neck and something went wrong when he fell,” Bowles said Saturday.
Trainers attended to Enunwa for several minutes before the receiver got to both knees before standing and then walking slowly to the locker room.
