The start of the group stage match between Mayo and Laois was delayed due to a protest by the players of both teams. Both teams wore t-shirts that said #UNITEDFOREQUALITY during the warm up and went back to the dressing room for approximately 5 minutes after the national anthem was played. The protest was about delays from the LFGA, Camogie Association and GAA to develop a charter for inter-county players. Other teams that played on July 1 also wore the same t-shirts.
