ESPN insider Chris Mortensen reported Tuesday evening that noted knee surgeon Dr. James Andrews operated on Bradford, smoothing out a bone spur, cleaning up ragged cartilage and removing particles from the knee, all things that could be responsible for the continuing pain that has rendered him unable to play for the past seven weeks.
The Vikings, who lead the NFC North at 6-2, made a decision to shut down Bradford for the rest of the 2017 regular season but if they make the playoffs and the veteran is healthy, the team could elect to activate him off IR. He saw Bradford on September 22 and determined then that no additional surgery was needed. Bradford sought out other options and received unsuccessful Regenokine treatments in October in hopes of reducing the pain and inflammation.
Backup Case Keenum has stepped up as the Vikings starting quarterback, leading the team to three straight victories since their win over the Bears at Soldier Field in Week 5. He'll earn $18 million in 2017 from the Vikings with a $14 million base salary and a $4 million roster bonus.
Bridgewater, whom the Vikings selected in the first round of the 2015 draft, has not played since the 2015 playoffs.
The Vikings' 2014 first-round pick tore his ACL and dislocated the left knee during a late August practice past year.
Bradford came over from the Eagles previous year in a trade after Bridgewater's injury.
He threw for more yards than any Vikings quarterback over their first two seasons.
