Priefer will serve the suspension during the 2014 regular season. The ban may be reduced to two games if Priefer also attends individualized anti-harassment, diversity and sexual-orientation sensitivity training.
"I owe an apology to many people -- the Wilf family, the Minnesota Vikings organization and fans, my family, the LGBT community, Chris Kluwe and anyone else that I offended with my insensitive remark," Priefer said in a statement. "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."
The review found that Priefer did make a single homophobic statement to Kluwe. The investigation also found that Kluwe was released for performance reasons, as well as the distraction caused by his activism, not his actual viewpoints.
