The team presented a check to school officials Friday. The Bears held summer training camps at the Platteville campus from 1984 to 2001.
The university was damaged June 16 by a tornado packing winds of up to 120 mph. Three residence halls sustained water damage and displaced roofs, and wind-swept debris smashed dozens of windows.
Two other buildings and the school's football stadium were also damaged.
The Pioneer Relief Fund is being used to support affected students and staff with food, clothes and temporary housing.
Chancellor Dennis J. Shields encouraged people to wear orange and blue Friday, the colors the Pioneers and Bears both wear.
