MINNEAPOLIS — Minnesota head coach P.J. Fleck has added three assistants and made two promotions in a staff shuffle for his second season.

Fleck announced Wednesday he’s hired Clay Patterson in a to-be-determined on-field coaching role and Donald Celiscar and Michael Priefer Jr. as graduate assistants.

Patterson was the head coach at Northeastern Oklahoma A&M the last two years. Celiscar played for Fleck at Western Michigan. Priefer, who attended Mound Westonka High School in the Twin Cities area and played defensive back at Wisconsin-Eau Claire, is the son of Minnesota Vikings special teams coordinator Mike Priefer.

Joe Rossi was also promoted from quality control assistant to defensive line coach, and special teams coordinator Rob Wenger added outside linebackers to his supervision. Bryce Paup moved from defensive line coach to pass rush specialist.
