Kansas City Chiefs wide receiver JuJu Smith-Schuster left the team’s Week 10 game against the Jacksonville Jaguars in the second quarter after taking a hard hit to the head, resulting in a head injury.

Chiefs quarterback Patrick Mahomes threw to Smith-Schuster in the middle of the field, when Jaguars safety Andre Cisco smashed his helmet into Smith-Schuster’s helmet. Smith-Schuster immediately went down and remained on the ground not moving for more than five minutes, with his hands held in front of his face in what appeared to be the fencing response that often occurs after a head injury.

After being examined by the team’s medical staff, trainers assisted Smith-Schuster to walk off the field and into the locker room. Officials threw a flag but then picked it up, ruling that there was no foul on the play. The Chiefs announced shortly thereafter that he had entered concussion protocol and would not return to the game.

Smith-Schuster had two catches for 33 yards on the day prior to his departure. The sixth-year pro has 46 receptions for 615 yards and two touchdowns in his first season with the Chiefs.
