Favre had surgery on the same ankle after a similar problem in 1995.
Favre said the week before the Packers' Dec. 31 season finale in Chicago that the pain was worse in practice because in games, you just "suck it up and go."
"I don't want to sound like John Wayne," Favre said. "It's not, 'Favre's walking around with knives sticking in his foot.' It's painful at times, but there's a lot of people who go through similar things."
