Bradford has played in one full game this season when he torched the New Orleans Saints in Week 1 for 346 passing yards and three touchdowns.
The Vikings activated the quarterback off injured reserve Saturday after a left knee injury sent him to the sideline earlier this season.
Bradford, who was placed on IR on November 8 with a left knee injury, returned to practice last week and completed his fifth practice Friday. He returned to practice last week, but coach Mike Zimmer said Friday he hadn't made a decision about whether to add Bradford to the active roster, while refuting a Boston Globe report that the Vikings would bring Bradford back.
If Bradford dresses for Sunday's game, he could serve as the backup behind starter Case Keenum.
On Sunday, the elder Jordan will be in the U.S. Bank Stadium crowd for the playoff game between the Vikings and the New Orleans Saints.
Zimmer did say that he believes Bradford is healthy enough to play should the Vikings need to rely on him in the postseason. The last time the Vikings lost at home in a divisional playoff game was in 1975, when the Cowboys beat them in the infamous Drew Pearson push-off game. The team also has reinforcements in quarterbacks Teddy Bridgewater and Kyle Sloter.
