Vikings TE John Carlson admitted that his 2012 season was a "debacle."

Carlson signed a five-year, $25 million last offseason. He sustained a knee injury in camp and never got going, catching just eight balls in 14 games. Now he's accepted a pay cut and is healthy. Carlson will enter camp as the clear No. 2 tight end behind Kyle Rudolph.

John Carlson has agreed to a restructured contract.

The Vikings foolishly gave Carlson a five-year, $25 million a year ago even though they had Kyle Rudolph ready to go. He ended up catching eight passes in 14 games. Due to count $4 million against the cap in 2013, Carlson was a lock for a massive paycut.

The Vikings would take a $4 million cap hit to cut John Carlson before the start of the league year, but would not owe him any more guaranteed money.

If Carlson is still on the roster by the first day of the league year, he will collect $1.2 million in guarantees. One of last year's worst free agent signings, Carlson was paid $7.9 million in 2012 to post an 8/43/0 stat line across 14 games. He has no role in the Vikings offense.

John Carlson (concussion) has resumed practicing.

He'll be good to go for Week 10 after missing two games. With just three catches on the year, Carlson couldn't be further from fantasy relevance in the Vikings' 30th ranked passing offense.

John Carlson (concussion) expects to resume practicing Wednesday.

Carlson has yet to officially gaine clearance, but he should be good to go for Week 10. With just three catches in seven games, however, he couldn't be further from fantasy relevance in the Vikings' woeful passing "attack."

John Carlson (concussion) has been officially ruled out for Week 9.

It will be Carlson's second straight absence. Signed to a five-year, $25 million deal in March, Carlson has three catches in seven games. He's week-to-week.

Vikings TE John Carlson (concussion) still has not been medically cleared.

It's not a surprise considering Carlson's long history of concussions. He's merely "week to week."

Vikings declared TE John Carlson, WR Jarius Wright, CB Brandon Burton, S Mistral Raymond, LB Audie Cole, and OL Mark Asper inactive for Thursday night's game against the Bucs.

Carlson suffered a concussion on Sunday, but he has been an utter disappointment this season anyway. The tight end sports a horrendous three catches for eight yards stat line. Rhett Ellison will back-up Kyle Rudolph. Raymond has been dealing with an ankle injury. McLeod Bethel-Thompson is the third quarterback.

Vikings TE John Carlson (concussion) has been ruled out for Thursday Night Football.

The owner of a 3/8/0 line behind Kyle Rudolph, Carlson is week-to-week. Take this as an opportunity to drop him if you forgot he was on your roster in a deeper league.

Vikings TE John Carlson's $1.2 million 2013 base salary is reportedly guaranteed for injury only unless he's on the roster as of the first day of the next league year.

Coach Leslie Frazier said Tuesday there is no reason to believe Carlson's fourth career concussion will put his career in jeopardy. The Vikes can, however, cut Carlson for performance reasons after he collects a whopping $7.9 million in guarantees this season. Carlson's contract is the one blemish on GM Rick Spielman's otherwise strong Executive of the Year candidacy. Fourth-rounder Rhett Ellison's emergence could make Carlson expendable going forward.
