Vikings Head Coach Mike Zimmer said Monday that, because Peterson is fully vaccinated, he would be able to return as soon as he has two negative tests 24 hours apart rather than waiting a mandatory minimum of 10 days.
Asked if that creates a possibility for Peterson returning by Sunday's game at Detroit, Zimmer said, "Yeah, we don't know."
"Not too many guys have passed those two negative tests, so you just have to let it play out and see where it goes," Zimmer said.
