Not only is Carlson out for the season, but it could end his career. He told the Minneapolis Star-Tribune this week that he will discuss the issue with his family during the offseason.
He has sustained at least three concussions since 2011.
"That's something that my wife and I will consider," he said. "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 suffered the head injury two weeks ago. He made eight starts this season and finished the season with 32 catches for 344 yards with one touchdown.
Carlson signed a five-year, $25 million contract with the Vikings last year.

San Francisco 49ers general manager Trent Baalke told radio station 95.7 KGMZ on Friday that any perceived tension between him and coach Jim Harbaugh is exaggerated.
"That's all overblown," Baalke said. "It's no different than it's been since Day 1. I think every relationship changes to a certain degree. But it's very professional. He's got a job to do. I've got a job to do. We try to do that together and we do it well together."
Team CEO Jed York said earlier this week that Harbaugh and Baalke often have creative tension over personnel decisions.
