Shane Kingston is not convinced that rules introduced to combat cynicism in hurling have made much difference to the game.

A tighter window for the advantage rule and a penalty plus sin-bin for denying a goalscoring opportunity inside the 20m line or 'D' were introduced for 2021.

But only a handful of such penalties have been awarded, and it still seems a little unclear as to what exactly it means "to pull down an opponent", the exact wording of a rule which does not apply to holding or pushing for example.

"Is there a bit of confusion there? I don't really know," the Cork forward told RTÉ Sport.

"You don't get a penalty unless you end up on the floor. I don't get it from that perspective.

"If you’re running through and you’re held up, you have to jump on the floor to get the penalty, I don’t know what the story is with it."

Cork have been boosted by the news that Colm Spillane (knee) and Bill Cooper (Achilles) are back in full training ahead of next week's Munster SHC semi-final clash with Limerick.

That will be a rematch of an Allianz Hurling League clash earlier this month in which the Rebels were well beaten but Kingston is adamant that defeat will have little effect on the championship encounter.

"We were happy enough with how the league went," he said. "We started off very well.

"We didn't perform too well against Limerick or Galway, so it was obviously disappointing as a collective and personally.

"Sixty-two minutes into the Galway game we looked like we were going to top the group and 10 minutes later we came fourth so we were obviously disappointed with that.

"But look we just have to forget about that, at the end of the day, it's the league and it's about trying to build, going into championship.

"Championship and league are very different. We know ourselves that Limerick are going to be a different animal.

"We just have to worry about ourselves and train as hard as we can, to put ourselves in the best position going into the Limerick game."
