EDEN PRAIRIE, Minn. (AP) -- The Minnesota Vikings have two key starters who must pass post-concussion tests before they can be cleared for action, tight end Kyle Rudolph and strong safety Harrison Smith.
They were hurt in the second half of Minnesota's loss at Chicago on Sunday.
Coach Leslie Frazier also said running back Adrian Peterson incurred a shoulder injury in the game. Middle linebacker Jasper Brinkley suffered a mild sprain of the AC joint in one of his shoulders. Right tackle Phil Loadholt developed some inflammation in one of his knees. But Frazier said none of them should have a problem playing this weekend against Green Bay.
Wide receiver Percy Harvin has missed the last two games with a sprained left ankle. Frazier had no update on his condition.
