MINNEAPOLIS — The Minnesota Vikings will suspend special teams coordinator Mike Priefer without pay for three games this season and donate $100,000 to lesbian, gay, bisexual and transgender rights groups, in response to former punter Chris Kluwe’s allegations of anti-gay slurs and taunts made by Priefer.

The Vikings announced the punishment Friday as part of a summary of findings by outside lawyers hired in January to investigate Kluwe’s accusations, which included a claim he was released because of his gay-rights advocacy.

The Vikings said Priefer’s ban could be reduced to two games at their discretion, provided he attends individualized anti-harassment, diversity and sexual-orientation sensitivity training.

Such education has been required for all Vikings employees, coaches and players on an annual basis for the past several years, the team said, and the improvements for the programs will be considered.
