Priefer's contract expired on Tuesday, and he won't be retained by coach Mike Zimmer after an eight-season run with the Vikings.
Mike Priefer, the Vikings special team coordinator for the past eight seasons, will not be retained, coach Mike Zimmer confirmed.
Priefer, 52, coached Vikings special teams from 2011-18. He was head coach for one game in 2016, a 17-15 Vikings loss to Dallas, when Zimmer was recovering from eye surgery.
He was also special teams coordinator for the Kansas City Chiefs (2006-08) and Denver Broncos (2009-10) before coming to Minnesota.
He sat out the first three games of the 2014 season as a suspension and had sensitivity training for making homophobic remarks at a special teams meeting the previous season.
