Cardinals rookie Marvin Harrison Jr was left dazed – and briefly unable to stay upright – after he was concussed by a brutal blow to the head.
The wide receiver, the No 4 overall pick in the NFL draft, had to be helped off the field after his helmet collided with the thigh of Green Bay linebacker Isaiah McDuffie.
In worrying scenes, Harrison Jr could be seen climbing to his feet before he stumbled and fell back to the turf while McDuffie looked on in concern.
The 22-year-old – son of Hall of Fame receiver Marvin Harrison – was taken off for evaluation in the injury tent.
Harrison Jr eventually walked into the tunnel before the Cardinals confirmed his afternoon was over.

‘WR Marvin Harrison Jr. (concussion) has been ruled out,’ Arizona said on social media early in the second half.
Harrison Jr is one of the most exciting prospects in football. He had 279 yards and four touchdowns from 17 receptions across his first five NFL games.
In Sunday’s 34-13 defeat by Green Bay, Harrison was twice targeted by quarterback Kyler Murray but did not have a catch.
The Cardinals also ruled out defensive tackle Bilal Nichols with a stinger. Nichols had one tackle in the game and 10 tackles in six games this season.
