Dublin hurling captain Eoghan O'Donnell reckons it 'makes sense' to tweak hurling's black card rule but is concerned about possible 'ambiguity' and the ability of referees to properly implement it.

Motion 27 for Saturday's Annual Congress proposes to make permanent the rule awarding a penalty, and black carding the guilty defender, when a goalscoring opportunity has been denied within the 20-metre line.
