The Vikings activated Bradford from injured reserve on Saturday, adding him to their 53-man roster a day before their NFC divisional playoff game with the Saints.
That game was arguably the best of Bradford's career, as he completed 84.4 percent of his passes for 346 yards and three touchdowns with zero interceptions.
Bradford hasn't played in a game since then, and went on injured reserve November 8 after having his third operation on his left knee the day before.
Bradford missed all but two games during the regular season with a knee injury. He made his return in Week 5 against the Bears, but was benched before halftime and hasn't played since.
Minnesota is slated to host New Orleans in the divisional round at 4:40 p.m. ET Sunday.
The Saints look to build on their home win last weekend against the Carolina Panthers and keep their Super Bowl aspirations alive as they take to the road to battle the defensively stout Minnesota Vikings in a contrast of styles that should make for a very exciting game.
Zimmer did say that he believes Bradford is healthy enough to play should the Vikings need to rely on him in the postseason.
