A Dungarvan club footballer played in a Waterford intermediate final on Saturday while awaiting the result of a Covid-19 test.
The player subsequently discovered that he had tested positive for the virus.
Waterford county board chairman Sean Michael O'Regan indicated that they would have looked favourably on a postponement request - if they had known of the issue in advance.
"There's no getting away from the fact that he got tested, I believe on the Thursday; results came back on the Sunday; and in between he played the county final on the Saturday, which is disappointing," O'Regan told the Herald.
"We have had incidences in Waterford that we've postponed matches, similar cases," he added.
"If we had known from the Dungarvan club, we could have looked at that … but we never got that opportunity, I suppose.
"In fairness to quite a number of people in Dungarvan GAA Club, I'm led to believe that a lot of those people didn't know as well.
"They're doing their due diligence now and finding out what went on."
O'Regan ruled out the possibility of an objection from Kill, his home club, who lost the IFC decider.
"There's nothing in the rule book there but, from a Kill GAA point of view, I don't see anything like that happening," the Waterford chief maintained.
The revelation comes as the GAA took the decision to suspend all club activity until further notice.
The decision has been taken by the Association's Management Committee in the interests of public safety "following a number of incidents that have been brought to our attention in recent days" according to a directive issued to counties today.
"In particular post-match celebrations and a lack of social distancing at certain events have proved disappointing and problematic," the directive states.
On Sunday evening video footage showed Blackrock Hurling Club celebrate their first Cork senior title with a parade of the cup involving many supporters in close congregation.
