There was a moment of high controversy in the first half of Wexford and Tipperary's thrilling All-Ireland semi-final in Croke Park as John McGrath had a goal ruled out.
Liam Sheedy's men thought they had raised their second green flag of the tie only for referee Seán Cleere to rule it out due to an earlier Lee Chin free which appeared to drop into Tipperary goalkeeper Brian Hogan's hands.
However, it turns out that the free actually went over the bar and Hogan caught it just after it sunk past. 32 seconds passed between the catch and the goal. The goal was eventually ruled out and Wexford were instead awarded a point.
An official explanation was read out on match-day broadcast RTE.
We have been told officially it is usually quicker than 30 seconds for them to make that decision and communicate it. The issue appears to be with communication to the referee. It is extremely noisy out there in Croke Park so maybe that has something to do with it.
Hawkeye uses four high-speed cameras at each end to locate the position of the ball up to 26 metres above the posts and 4 metres outside each post. The official can not communicate with the referee to stop open play.
Hawkeye innovation's GAA section outlines the process as communication "via an audio signal relayed to the referee within seconds of the sliotar crossing the line".
Play did stop briefly between the catch and the goal when Tipperary were awarded a free.
Speaking on RTE, former Waterford hurler Ken McGrath said the crowd's reaction came about because of confusion.
"I think the crowd got incensed because they did not know what happened. They thought it was a free out because of a foul."
