Referee Hand Signals
To allow the referee to communicate information about stoppages of play and penalties the NAH has implemented the use of hand signals. They are simple and effective – one look at the ref and you know he saw you lean into the innocent off-ball opponent. I’m not sure how much use they’ve seen in the qualifiers because they take a little more experience to master.
Peep this cheat-sheet so you don’t start chirpsing before you know what you got called on.
