There’s been a lot of talk about the Vikings going after opposing defenses with a two tight end set featuring sophomore Kyle Rudolph and fellow Notre Dame alum John Carlson. That dangerous duo is now in question though after Carlson reportedly sprained his MCL today in practice.

John Carlson was signed this offseason as a free agent. The amount of his contract raised some eyebrows amongst Vikings fans considering Carlson was out with a shoulder injury the entire 2011 season. Now it looks like Carlson could potentially miss some playing time depending on the severity of the injury.

When asked by the media if the injury could cause Carlson to miss playing time, Frazier said, “It could. It could. We’ll see. They’ll tell me more when we get back in.”

Carlson was supposed to get an MRI today to make sure the injury isn’t a tear. We’ll keep you updated when those results come back.
