The coach, who was not identified, allegedly stepped onto the field after a game and pulled down his pants, exposing his backside to the team of girls, the San Francisco Chronicle reported Monday.
Several of the girls and their parents called the police asking for misdemeanor indecent exposure charges against the coach, said Windsor police Sgt. Steve Brown.
The coach was leading his team in an under-16 tournament game that had featured physical play and "heated arguments," Brown said in a written statement.
Police officers spoke to the coach, who has been suspended, but he denied exposing himself.
