Does the school have a "No school No Play" Policy? The district my daughter is in has the policy of where if you are not in school the day of the game for whatever reason you can not play in a game that day. So my question would be, did she miss the whole day of school?
That's the way it is in my DD's school district....and if you ain't there by 10:00am, Doctor's, Denist, Funerals, court, etc.... you can't play that day....period....
So maybe that's the case here....if not and just something the coach decided then he or she should be ashamed of themselves and publicly called out for it....
