The Minnesota Vikings have confirmed that tight end John Carlson has been placed on their injured reserve list.

Carlson sustained a concussion earlier in the season and as a result of the injury the Vikings have decided to end his season for his safety by placing him on IR.

The 29-year-old has admitted that he is considering his future in the game after sustaining his third concussion since the 2011 season.

Carlson told the Minneapolis Star-Tribune: "That's something that my wife and I will consider.

"After every season it's an evaluation period because of the nature of our business. Players move around, players get cut, coaches get fired, things happen.

"So in that sense, every year is an evaluation period and this year will be no different. And the concussion part of it will be in that conversation."

Carlson has 32 receptions for 344 yards along with one touchdown this season.
