Armagh great Oisin McConville is worried by what he saw over the weekend as football returned with some tweaks in the rulebook.
The Orchard legend is concerned that the new rules could encourage 'gamesmanship' amongst forwards and questioned why the advantage rule was tinkered with.
It comes as a new rule which means a penalty and sin bin is awarded for a cynical foul preventing a goal scoring opportunity - a law exercised twice in Dublin's victory over Roscommon yesterday.
Although McConville admits that time is needed to see the impact of the rule changes, he does have his concerns for the knock-on effects the changes could have.
"The big one was the Dublin-Roscommon game where we had a couple of penalties that you could question," McConville told Morning Ireland.
"I think once we leave it to the discretion of the referee, we're going to create issues for ourselves.
"The advantage rule is a significant one. The advantage rule was something that I felt had actually worked quite well and I don't understand why we tinkered with it.
"It's early stages, I do understand that we have to address the cynical end of things. But I do think also that we are encouraging a bit of gamesmanship. I think we saw a little bit of that at the weekend.
"That's hopefully something we can eradicate pretty quickly and it's hopefully something referees can stamp down on and realise the difference between someone who throws themselves to the ground and is genuinely being tackled in a cynical way.
"It's suck it and see for a while but on the evidence of what we've seen, I'd have a bit of concern about it."
