Kyler Murray has been ruled out for Sunday's Vikings game against Chicago due to a concussion suffered last Sunday against Green Bay.
That means Carson Wentz will be under center with J.J. McCarthy as the backup.
Former Viking Chad Greenway, and analyst on Audacy's "Inside the North," talked to Chad Hartman about how long a player should be sidelined with a head injury as Murray advances through the NFL's concussion protocol.
"And if we're really going to be serious about the health of players, it's something you should definitely look at," Greenway explains. "And just kind of gauge how many of these concussions, these player's concussions, that are confirmed are coming back in week one. And what's the longevity of those guys and how's that affecting them?"
Murray was a limited participant in practice all week and simply ran out of time to make more more progress after taking an illegal hit to the head in the first quarter of his debut for Minnesota in the season opener.
Vikings coach Kevin O'Connell said he expects Murray to clear the protocol early next week and be able to play at Tampa Bay on Sept. 27.
Murray took a jarring hit to the side of his helmet that drew an unnecessary roughness penalty on Green Bay safety Javon Bullard, leaving Murray on the turf in the type of defensive pose that can accompany brain trauma.
But the eighth-year player — who signed with the Vikings after being released by Arizona — was eventually able to slowly walk off the field under his own power. He was alert and interacting with teammates in the locker room afterward and looked spry on the practice field this week.
Wentz threw three touchdown passes in relief of Murray to help the Vikings close the game with 29 consecutive points in their 39-22 victory. J.J. McCarthy will be the No. 2 quarterback at Chicago. Against Green Bay, McCarthy was the emergency No. 3 quarterback who can only enter the game if the first two are injured.
The Vikings also ruled out wide receiver Jajuan Jennings, who hasn't practiced all week because of a personal family matter.
Right tackle Brian O'Neill was listed as questionable with a knee injury and running back Jordan Mason is out for at least four games because of a broken thumb.
Kickoff slated for noon Sunday.
