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.

This was understandably booed by the Dublin fans as the referee could not award the point to O'Sullivan.
Dublin held a six-point lead at that stage of the match, fifteen minutes into the first half, but would go on to draw the game as Galway launched a second-half comeback.
And some GAA fans were not impressed with Hawk-Eye's role in the match.
One person said: "How can you have no Hawk-Eye available? Dublin denied a clear point in the hurling. Absolutely shocking stuff."
Another said: "Dublin should've won by a point! Hawk-Eye robbed them!"
Hawk-Eye was first introduced for all Championship matches at Croke Park in 2013.
But the technology has not always been warmly received and has made some contentious decisions in recent seasons.
Last season it was stood down for the All-Ireland football semi-final between Kerry and Dublin after appearing to make errors during the first-half of the preceding semi-final between Derry and Galway.
The technology did work when called upon for another decision during the second half.
