Bradford missed all but two games during the regular season due to a knee injury, and he was placed on injured reserve.
If Bradford is activated and dresses for Sunday's game—likely as Case Keenum's backup—Volin noted it is unclear what that means for quarterback Teddy Bridgewater's status.
Keenum started 14 games in place of Bradford and enjoyed a career season, highlighted by an 11-3 record.
The 29-year-old journeyman threw for 3,547 yards, 22 touchdowns and seven interceptions to go along with 160 yards and one score on the ground.
Of the two starts Bradford made during the regular season, one of them was coincidentally against the Saints.
In that contest, Bradford had one of the best games of his career with 346 yards, three touchdowns and no interceptions en route to a 29-19 win.
If Bradford is active Sunday, it suggests Keenum could potentially be on a short leash despite the success he enjoyed during the regular season.
Neither Bradford nor Keenum have ever appeared in a playoff game, while Bridgewater started a postseason game for the Vikes during the 2015 campaign.
