GAA fans have slammed Hawk-Eye as 'a joke' after it failed to work during Sunday's Leinster Hurling Championship match between Dublin and Galway.
The video technology was called for by the match umpires when Dublin's Cian O'Sullivan struck an effort towards the goalposts.
But as everyone awaited the verdict from Hawk-Eye, the system refused to play ball as a message saying "Hawk-Eye Data Unavailable" was displayed on the big screens at Croke Park.
