There was confusion over the final score in Tipperary's All-Ireland semi-final victory over Kilkenny.
The scoreboard in Croke Park - and the tally on RTÉ - had Tipperary victorious by 4-21 to 0-30. However, that Tipperary tally appears to include a late Noal McGrath point that was waved wide by the umpires.
It is unclear if the signal was incorrect and the score was good, or if the Croke Park scoreboard was incorrect.
The match officials, including referee James Owens, were seen conferring for some time on the field following the final.
RTÉ's have since confirmed that the final score of 4-21 to 0-30 is correct.
