Former Minnesota Vikings punter Chris Kluwe on Friday said he would file a lawsuit alleging discrimination against his former employer.

The announcement came after the Vikings said they will suspend special teams coordinator Mike Priefer without pay for 3 games and donate $100,000 to LGBT rights groups.

In January, Kluwe alleged that he was fired from the team by Priefer, then-head coach Leslie Frazier and general manager Rick Spielman.

Kluwe claimed that Priefer made several anti-gay comments in the course of objecting to his advocacy on the issue of marriage equality and quoted 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 hired outside counsel to investigate the claims.

On Friday, the Vikings released a summary of the investigation.

Priefer apologized in a statement from the team: “I regret what has occurred and what I said. I am extremely sorry, but I will learn from this situation and will work on educating others to create more tolerance and respect.”

Clayton Halunen, Kluwe's attorney, said the complaint will be filed as early as Monday.

“Here we have this company, this Minnesota company who's getting 400 million out of taxpayers' funds to build the stadium, and yet they are violating state law by engaging in discriminatory conduct, and that is unacceptable,” Halunen is quoted as saying by the AP.

The lawsuit also alleges defamation and wrongful interference of a contract.
