Ejection

[Hawks Coach]

Tell coaches that inquire about a player or coach's eligibilty to participate in the game that they need to take it up with the leauge, tournament, or whoever runs the show. Refs aren't responsible for ensuring that players or coaches comply with suspensions, age requirements, etc.

And that is one of the few reasons you will normally see a result overturned in my experience - participation of ineligible personnel.
