​After leading the Vikings to a dominant Week 1 win against the now NFC South division leader, the New Orleans Saints, Sam Bradford has been unable to stay on the field.

Following the Week 1 win, Bradford's knee hasn't been healthy enough to get him into game action. Sam actually started for Minnesota in their Week 4 win against Chicago, but threw only 11 passes before being removed from the game because of his injury.

With Bradford out, and Keenum their current starter, Minnesota has been waiting on the return of Teddy Bridgewater. 

Yesterday, Bradford got his knee scoped and since he's due to miss more time, the Vikings opted to place him on the IR to make room on the active 53-man roster for Teddy.

​​With just eight weeks left in the season, this move spells the end for Bradford at least until the playoffs, but he won't see anytime then unless both Keenum and Bridgewater can't go.

The latest news also has big implications for Bradford's career. As he tries to return and finally put his knee issues in the past, the next time he takes the field may be for another team. 

Bradford is now 30 years old and his contract ends following the 2017 season. If Bridgewater stays healthy in the meantime, it's highly unlikely Minnesota opts to bring him back, especially for the $14 million he's due to make.

Hopefully for Bradford this isn't the end, but rather the beginning of great comeback story.
