Based on these recent reports regarding Bradford, Minnesota placing him on injured reserve in order to make room for Bridgewater this week seems pretty likely.
Bradford underwent an arthroscopic procedure Tuesday in which Dr. James Andrews "cleaned up" the left knee but found no major damage, team sources told ESPN's Chris Mortensen.
However, Bridgewater will remain behind Case Keenum, who will get the start Sunday against the Redskins.
Bradford was injured in Week 1 against the New Orleans Saints and re-aggravated his ailing knee again against the Chicago Bears.
Bridgewater was placed on the PUP list to start the season, and he returned to practice October 18, the first day he was eligible.More news: Amazon Launches New Fire TV Stick For International Customers

Bradford, who was acquired via trade from the Eagles after Bridgewater's injury, started the season opener but suffered a non-contact injury shortly thereafter.
Bridgewater hasn't played since the 2016 preseason, when he dislocated his knee and required surgery.
The quarterback missed all of the 2016 season after tearing his ACL and dislocating his knee during a non-contact drill in a preseason practice past year.
While Sloter has yet to play a down in 2017, sources confirmed the Vikings did not want to risk losing him by releasing him to the waivers market. He was a Pro Bowl selection in 2015 when he passed for 3,231 yards and 14 touchdowns against nine interceptions.
