For High School League games, if a coach is ejected, it is either a $100 fine or a 1-game suspension (minimum, based on level of offense). Personally, I'd pay the $100 and get on with the next game. For the second offense, the penalty is doubled ($200 or 2-game suspension). Max for "normal" unsportsmanlike conduct is $300 and probation of the program for a year. "Serious" unsportsmanlike conduct is up to $500 and suspension of the program from the League for a year. For non-League contests, I don't know what the penalty is.
That help?
