The advanced mark has polarised GAA players, pundits and supporters alike since they were implemented at the turn of the year.
A mark can be called when a forward or defensive player catches a ball cleanly that has been kicked from on or outside the 45 metre line - once the ball has travelled at least 20 metres.

The player awarded an advanced mark will then have 15 seconds to take a kick. For attacking catches within the 13-metre line, the play is brought back to that line.
So will this make it harder for teams to play overly defensive? Or is it an overly complicated, convoluted change that will cause too much confusion?
On RTE's Allianz League Sunday, the panel was loath to completely dismiss the rule change.
"There's 16 league games played, and probably on average two or three marks per game, so the body of evidence isn't there yet," said Kevin McStay.
"It's only round one. We'll see maybe after the fourth round or so.
"Personally I think, tactically it has great potential... but I think there's plenty of room for chaos as well. The jury is out, but it has potential."
Sean Cavanagh believes it could allow smaller counties to be more competitive as the year progresses, though he does have some concerns over the overall impact of the law.
"I'm probably on the fence at this stage," said the Tyrone man.
"In the games I've watched it hasn't has a massive impact. I can see the positive where some weaker sides may tactically work on this to try and close the gap between them ans some big teams.
"It may make the games more competitive... but two out of ten of the marks we saw between Saturday night and today were guys running out and catching it chest height, and that's wrong."
