Three men have been arrested for allegedly beating the crap out of superstar college running back Montee Ball near the University of Wisconsin campus.
Cops say the three men are all 21 years old ... and have each been charged with battery for the August 1st attack on the 2011 Heisman Trophy finalist.
One of the men who was arrested had sustained serious injuries during a fight at a house party a few days before the campus attack.
The man suffered serious injuries to his face and head in the attack ... and told police Ball was involved in the attack.
Cops later determined Ball was at the house party when the fight went down. Ball has denied participating in the fight.
The man who was beat up at the house party told investigators he did NOT order a retaliatory strike on Ball.
