Former University of Michigan quarterback Denard Robinson is returning to the Big House as a judge for the 2014 Polar Plunge.
The current Jacksonville Jaguar is to join his old coach, Brady Hoke, on the panel judging Saturday's event that benefits Special Olympics of Michigan.
Plungers get to change in the stadium's locker rooms and walk through the tunnel. They take the plunge on the field, inside a pool.
The top fundraiser will receive four tickets to the Michigan vs. Miami of Ohio football game and six tickets to the Michigan football team's preseason fall practice at Michigan Stadium.
Participants can attend the Polar Plunge free of charge, and it costs $10 per person for guests. Each plunger gets two complimentary tickets to the Michigan women's basketball game against Iowa.
