Former Vikings punter Chris Kluwe says he was subjected to homophobic language late in his tenure with the team, and eventually cut, because he spoke out in support of gay marriage.

Kluwe says that Mike Priefer, the Vikings’ special teams coach, was openly prejudiced against gays and intolerant of those who support gay rights. Kluwe also says that Vikings General Manager Rick Spielman and former head coach Leslie Frazier ultimately decided to get rid of him because they didn’t like him expressing his views.

“I was fired by Mike Priefer, a bigot who didn’t agree with the cause I was working for, and two cowards, Leslie Frazier and Rick Spielman,” Kluwe wrote at Deadspin today.

Frazier was fired this week and Priefer’s future with the Vikings is unclear, but Kluwe says that Priefer shouldn’t be a coach with the Vikings or anyone else.

“If there’s one thing I hope to achieve from sharing this story, it’s to make sure that Mike Priefer never holds a coaching position again in the NFL, and ideally never coaches at any level,” Kluwe wrote.

At a time when the NFL is investigating the Miami Dolphins for allegedly allowing Richie Incognito and other players to bully Jonathan Martin, Kluwe paints a picture of Priefer that may force the NFL to launch another investigation.
