Jim McGuinness will reserve judgement on the introduction of the black card ruling until after the Allianz League is completed.
The Donegal manager saw his team lose 0-13 to 1-7 against Tyrone in the Dr McKenna Cup Section A yesterday when just one player - Rory Kavanagh - fell foul of the new rules.
“It’s very hard to know in terms of how it develops over the course of a few months,” McGuinness said. “By the end of the league, people will have a clearer idea. There wouldn’t have been enough there for me today to make a judgement.”
McGuinness accepted match referee Barry Cassidy’s decision to black card Kavanagh for blocking off Tiernan McCann on 59 minutes, moments after Martin O’Reilly left the field with concussion.
The new ruling was passed at Annual Congress following the proposal of the Football Review Committee last year, which outlaws cynicism in the form of tripping, pulling down and body-checking.
The offender must be replaced, as Kavanagh was by Antoin McFadden. After three black cards no substitute is allowed.
“Somebody said if you grab somebody and don’t let them by you but don’t pull them to the ground, it’s not a black card,” McGuinness noted.
“If you’re strong enough to hold somebody up, it’s not a black card? All these things are interpretation of the rules and the referees implementing them. It wasn’t that difficult to referee today.
“I think 99 per cent of managers coach to the rules. The Rory Kavanagh one happened after an incident with Martin O’Reilly and the game heated up. It was a rush of blood to the head on the back of what happened.
“That’s where black cards will appear. When the intensity of the game rises and something happens, or you feel hard-done by and your blood’s flowing, then someone comes across you and you block a run — that’s when it happens.
“That was it prior to the implementation of the rule and it will happen again in the future.”
