The Minnesota Vikings will release tight end John Carlson, according to multiple reports, Tuesday afternoon.
Carlson, 29, considered retirement for a point during the offseason, but elected to resume his football career after ending his second season on injured reserve in the last three years, according to 1500 ESPN.
The Litchfield native was due $3.9 million in base salary in 2014. He filled in for the injured Kyle Rudolph near the end of the season, but suffered his fifth reported concussion and ended the year on injured reserve.
Carlson finished 2013 with 32 catches for 344 yards and a touchdown.
He had restructured his deal with the Vikings prior to the start of the 2013 season and, according to FOX Sports Mike Garafolo had been in discussions about doing it again in the offseason.
NFL.com reports that he lasted just two years into a five-year, $25 million contract that was signed in March of 2012. In all, Carlson collected $9.55 million in guarantees over two seasons while catching 40 passes for a total of 387 yards and one touchdown.
Carlson was originally a second-round draft pick by the Seattle Seahawks in 2008. He played college football at the University of Notre Dame.
