Arizona Cardinals wide receiver Marvin Harrison Jr. suffered a concussion during a game against the Green Bay Packers after colliding with linebacker Isaiah McDuffie's thigh.

Following the injury, Harrison was ruled out for the remainder of the game.

This injury is a significant setback for Harrison, who had been leading the team with 17 catches for 279 yards and four touchdowns in his rookie season.

Initially, Harrison attempted to continue playing but stumbled, prompting his exit to the injury tent.

Cardinals coach Jonathan Gannon expressed uncertainty about the severity of Harrison's injury after the game.

At halftime, the Cardinals were trailing the Packers 24-10, and Harrison had not recorded any catches on two targets before his injury.

In a separate incident, New Orleans Saints receiver Chris Olave was evaluated for a potential concussion after a helmet-to-helmet hit during a game against the Tampa Bay Buccaneers.

Olave was slow to get up after the hit and was later ruled out for the remainder of the game due to a concussion.

This injury to Olave adds to a troubling trend of concussions affecting notable wide receivers this season.

The Saints are scheduled to play against the Denver Broncos on Thursday night, marking the start of Week 7 in the NFL.

Video footage of Harrison's injury showed him initially getting up but then falling back to the ground, appearing dazed.

Harrison's concussion raises concerns about his availability for the upcoming week, as he must clear the concussion protocol.
