KANSAS CITY, Mo. — Chiefs wide receiver JuJu Smith-Schuster was ruled out of Sunday’s second quarter game against the Jacksonville Jaguars after entering concussion protocol.
Smith-Schuster was crossing the middle to catch a pass from Patrick Mahomes when Jaguars safety Andre Cisco slapped him high, drawing a warning from the referee.
The wide receiver was motionless on the turf, his hands momentarily frozen in a concussion reminiscent of the concussion suffered by Miami Dolphins quarterback Tua Tagovailoa earlier this season.
Smith-Schuster eventually stood up with the help of teammate Travis Kelce and left.
While he was motionless on the ground, referee Brad Rodgers picked up the flag and declared no penalty, although replays showed helmet-to-helmet contact.
The Chiefs’ leading wide receiver this season (46 catches, 615 yards), Smith-Schuster had two catches for 33 yards against the Jaguars.
Kansas City also lost right tackle Andrew Wylie to an elbow injury, while backup cornerback Chris Ramones was ruled out after entering concussion protocol.
