Both counties released statements this morning with Clare's the stronger, claiming the governing body have shown contempt and disdain for the players.
A statement from the players – made via the Women's GPA – says they feel hugely disrespected by the idea that a coin toss would decide who progresses.
The sides were due to meet at Semple Stadium on Saturday.
Meanwhile Tipp and Cork are continuing their preparations for the other quarter-final in Thurles which throws-in at 4 o'clock.
