Brian Gavin: Refereeing jury remains out on merits of advanced mark

The new rules had their first official airing this past weekend in the five O’Byrne Cup games, and it was encouraging that the Leinster Council brought in the five referees last week to brief them in advance.

Referees have to be up to speed with the sin bin, the advanced mark, and the 20m kickout more than anybody else, and if their understanding of it is clear then that will filter down to the stands and terraces.
