Donal Óg Cusack says the incident that resulted in Joe Canning's injury has highlighted an anomaly in the law that needs to be addressed. 

The 2017 Hurler of the Year will miss the entirety of this year's Leinster Championship after injuring his groin in a collision with Waterford's Kevin Moran during last Sunday's Allianz Hurling League semi-final in Nowlan Park. 

Referee Paud O'Dwyer adjudged the incident a fair shoulder-to-shoulder challenge and only awarded a 65 to Galway following the subsequent clearance. This was in accordance with the rules which, unlike in football, allow a shoulder-to-shoulder challenge even when the attacking player is in the act of striking. 

And Cusack, feels, having reviewed the footage which showed Canning to be off balance and in the act of striking when shouldered, that this an anomaly in the law which needed to be addressed. 

"It's Jamie Barron who is in pursuit of Joe Canning and their right feet get entangled so Joe is off balance by the time Kevin Moran comes in to hit him," Cusack said on League Sunday

"I know people talk about shoulder to shoulder but it's the spirit of this that's important. And paramount is the welfare of the player.

"There is provision in the rulebook to protect the kicker in football. Yet it isn't there for hurling. That's an anomaly that needs to be addressed straight away.

"I would appeal to the powers that be that they need to address that situation and bring the same protection for the hurler that's there for the footballer.

"And they need to err on the side of protecting the player because nobody wants to see any hurler, let alone Joe Canning, injured in that way."
