A surge by fans determined to get onto the pitch at the end of the Cork/Limerick hurling match last weekend resulted in a teenage girl needing medical attention.
The girl had to pulled be to safety by a steward as a decision was taken to open the gates at the Blackrock end of Supervalu Páirc Uí Chaoimh to ease the pressure on the terraces.
In the wake of the incident, Munster GAA has renewed it's appeal to supporters not to enter the field of play after matches.
RedFM's GAA Correspondent Ger McCarthy who was at the match, says in recent matches at the Páirc the Blackrock end has been the busier of the two terraces.
"I've noticed in the last bunch of matches at SuperValu Park Uí Chaoimh, when there's a big crowd there, the Black Rock end has become kind of like a big terrace where you have the flares and your flares going off, a lot of singing and dancing and it does add to the atmosphere. But we don't want that atmosphere to spill out onto the pitch and upset or hurt anybody. We don't want that to become the norm."
