Referees have been called to a non-scheduled meeting tomorrow to discuss some decisions made in Championship games.

According to the Irish Independent the meeting has been called following a number of mistakes by experienced officials in the Championship so far.

The new black card system has been in operation but there have been inconsistencies in its application.

Criticism has come from the likes of Mickey Harte who has questioned the consistency of refereeing calls made in the first game between Tyrone and Down in the Ulster Championship.
