NFL Network Insider Ian Rapoport reported Monday that Bridgewater is expected to come off the physically unable to perform list before Wednesday's deadline, according to a source informed of the situation.
Keenum has played well during the Vikings' four-game winning streak ahead of their Week 9 bye. The 29-year-old is completing 63.9 percent of his passes on the season and earned 6.9 yards per attempt, with seven touchdowns to three interceptions.
Sticking with Keenum would give Bridgewater more time to get back into a groove after the devastating knee injury wiped out all of 2016 and had some questioning whether the former first-round pick would ever play again in the NFL.
Bradford, who has missed six games and is still dealing with a knee issue, could be the odd man out. Rapoport reported, however, no decision has been made whether to shut down the team's opening-day starter.
