Next season’s McGrath Cup may not go ahead after Limerick and Clare withdrew in protest at the seeding of the Munster Championship.
Munster council secretary Simon Moroney said the pre-season tournament is in danger if Tipperary and Waterford pull out.
Quoted in the Irish Examiner, Moroney said: “We're currently asking counties whether they are or aren't competing and then we'll make a decision whether to proceed if there are low numbers.
"Occasionally, some of the counties and colleges don't participate in one or other of the codes and we have a regulation that allows withdrawals taking into account the actual participants.
“But obviously with the four county panels having indicated they wouldn't participate in it, we will consider that and how to proceed.”
