The Minnesota Vikings on Friday launched an investigation into Chris Kluwe's claims that his gay marriage advocacy ended his NFL career.

Former Chief Justice of the Minnesota Supreme Court Eric Magnuson and former Justice Department attorney Chris Madel will head the investigation.

“It is extremely important for the Vikings organization to react immediately and comprehensively with an independent review of these allegations,” team president Mark Wilf said in a statement.

In a scathing op-ed published Thursday, Kluwe said that he was fired by special-teams coordinator Mike Priefer, whom he called a “bigot,” and two “cowards”: then-head coach Leslie Frazier and general manager Rick Spielman.

Kluwe alleged that Priefer made several anti-gay comments in the course of objecting to his advocacy on the issue of marriage equality and quotes Priefer as saying during a team meeting, “We should round up all the gays, send them to an island, and then nuke it until it glows.”

Priefer “vehemently” denied the charges and the Vikings said that Kluwe was released as a result of his “football performance.”

Speaking to the AP, Kluwe said that he was pleased that the Vikings team was taking the matter seriously.

“I made some very serious statements and I do have the evidence to back them up,” Kluwe said. “I don't think [Preifer] is a good role model.”
