The new sin bin rule in Gaelic Football was put to the test in Clones today as Monaghan welcomed Dublin in the Allianz League.
John Small received an early black card for Jim Gavin's men and, as per the new rule, was sent to the sin bin for 10 minutes.
While that was straight forward, there was confusion later in the half. Robbie McDaid came on for Michael Darragh Macauley as a blood sub but just when Macauley was about to re-enter the play, McDaid received a black card and was sent to the bin.
As that was happening, Macauley had made his way back onto the pitch.
The play resumed but referee David Coldrick then blew up, approached the Dublin bench and ordered Macauley off with the Dublin midfielder forced to sit it out for 10 minutes because of McDaid's misdemeanor.
