KANSAS CITY, Mo. — Chiefs wide receiver JuJu Smith-Schuster was ruled out of Sunday’s game against the Jacksonville Jaguars in the second quarter after entering the concussion protocol.
Smith-Schuster was going across the middle to catch a pass from Patrick Mahomes when Jaguars safety Andre Cisco hit him high, drawing flags from the officials.
The wide receiver was left motionless on the turf with his hands momentarily frozen in a scene reminiscent of the concussion suffered by Miami Dolphins quarterback Tua Tagovailoa earlier this season.
Smith-Schuster was eventually helped to his feet and walked off with assistance from teammate Travis Kelce.
While he was still motionless on the ground, referee Brad Rogers picked up the flag and announced there was no penalty, even though replays showed helmet-to-helmet contact.
The Chiefs’ leading wide receiver this season (46 receptions, 615 yards), Smith-Schuster had two catches for 33 yards against the Jaguars.
Kansas City also lost right tackle Andrew Wylie for the game because of an elbow injury, while backup cornerback Chris Lammons was ruled out after entering the concussion protocol.
The Chiefs won 27-17 to improve to 6-2.
