Winfield has missed the last two games and was hoping to be ready to play coming off the Vikings' bye week. He practiced in full gear all week but said he still feels pain when he plants on the foot.
"I've been out the last couple of days running on it, testing it," Winfield said. "It's good going forward, but I still have a little problem cutting. But I would say next week I should be OK."
Winfield said he doesn't want to rush back and risk further injury that would keep him out longer.
"A lot of guys try and come back from injuries real early and something else happens," Winfield said. "Hopefully we won't do that."
