Concerned with Sam Bradford's knee, Vikings promote practice squad QB


The quarterback experienced pain, swelling and discomfort in his left knee following the Vikings' season-opening win over the Saints - the same knee he had surgery on in 2013 and 2014 to fix a torn ACL.

The Vikings veteran quarterback is coming off an impressive performance against the New Orleans Saints on Monday Night Football, completing 27-of-32 passes for 346 yards.

The Minnesota Vikings have an interesting situation on their hands with the recent reports of Sam Bradford having a bit of a concerning injury heading into week two. Adam Schefter added that the "Vikings have guarded optimism but concern" about Bradford's left knee injury, which did require an MRI this week. While the common belief is that Bradford will still play against the Pittsburgh Steelers on Sunday, his knee injury still reportedly required an MRI earlier this week. It is the same knee that underwent ACL repairs in 2013 and 2014, when Bradford was with the Rams.

This means one of two things: The Vikings are either concerned that Bradford won't be able to get through Sunday's game, meaning Case Keenum will need a backup, or they already are preparing for Keenum to start and Sloter will be his backup.
