That seems like a long shot at this point.
"We're holding out hope that there's a chance between now and what happens Sunday at noon," Frazier said. "We'll see how he feels tomorrow when he wakes up, as well."
Losing Winfield would be a big blow to a Vikings secondary that has struggled to create turnovers and make big plays during their 0-4 start. He's one of the best tackling cornerbacks in the NFL and moves from outside to cover the slot receiver in nickel situations.
Winfield was unavailable for comment Friday.
If Winfield cannot play, Asher Allen likely would take most of his snaps at nickel back. Allen has played sparingly in two games this season because of an injured toe, but he deemed himself ready to go this week. Chris Cook would start in Winfield's place.
