Sloter isn't expected to dress for Sunday's game against the Redskins, Ben Goessling of the Minneapolis Star Tribune reports.
Sloter had been acting as the Vikings' No. 2 quarterback behind starter Case Keenum the past three games while Sam Bradford (knee) was unavailable. Though Bradford was placed on injured reserve and isn't likely to return this season, the team activated fellow signal caller Teddy Bridgewater (knee) from the Physically Unable to Perform list in a corresponding move, pushing Sloter down a rung on the depth chart. He could be inactive for each of the Vikings' final eight games if both Keenum and Bridgewater remain healthy.
His promotion from the practice squad could indicate Sam Bradford's knee injury is more serious than first thought. Bradford is expected to play Sunday, but is questionable with a knee injury. Backup Case Keenum would start if Bradford can't play with Sloter serving as the third string quarterback.
Sloter was signed to Minnesota's practice squad, Minneapolis Star Tribune reports.
The Vikings agreed to pay him a higher than the usual $20,000 per week salary. He could be a long-term project for the Vikings as a result.
