Washington was leading the game, 20-13, with just under 3 minutes left before halftime when the fight began, according to the Michigan City News-Dispatch. The fight began after a Washington defensive player wall flagged for unsportsmanlike conduct for a late hit on a Michigan City player, the News-Dispatch reported.
Players started shoving and it quickly escalated into a fight between a swarm of players on both sides. Police stopped broke up the brawl after attempts by coaches and players failed.
Officers then met with school officials and a decision was made to call the game, according to The South Bend Tribune.
Michigan City police Officer Dion Campbell said the game was halted because so many players were ejected that neither team would have had enough players to continue.
