Texas high school football coach Mack Breed, who was accused of ordering players to hit a referee, has resigned, and state officials warned Thursday that other punishments may be coming to those involved, according to the Associated Press.

Breed was an assistant football coach at John Hay High school in San Antonio. Breed reportedly admitted to telling two players to intentionally target a referee who had allegedly been using racial remarks during the game.

Video of the two players hitting the referee was seen across the United States, as this became a big topic in news and high school sports. Since the hit, both players, Michael Moreno and Victor Rojas, have stated that they wish they could take the hit back, according to ABC News. Rojas and Moreno have since been assigned to a different school and have been prohibited from going to John Jay football games as spectators. Both boys will be eligible to return to John Jay High School next semester, according to ESPN's John Barr.

High school football has been at the forefront of controversies this September. A New Jersey high school football player was removed from his team after taking an opponent's helmet off and then using it as a weapon to hit the player in the head. Football controversies have been major topics the past few years, as violence in the sport has proven to lead to major issues. Breed's resignation is a sign for change, at least at John Jay High school.
