GAA referees chief Donal Smith admits implementing and communicating the new sin bin/penalty in hurling will be a challenge.

Now that it and other rule changes such as the adjusted advantage rule and concussion substitute will be part of the inter-county season when it commences, it is up to the national match officials manager to ensure they come into effect clearly and are understood.
