It was a bad day for the Rebels in Croker on Saturday as the Dubs cruised past towards the final four of the All Ireland.
Thousands of Cork fans made the journey to Dublin for the match, with one being diehard Rebel Roy Keane who appeared on the big screen just before the 50 minute mark.
And when the Manchester United legend appeared on the big screen, the stadium started to boo in unison. The Corkman took it well though and laughed off the incident.
Many took to Twitter to comment on the bizarre incident that they had just seen, with one saying:"#RoyKeane just got booed at Croke Park."

50,874 football fans attended yesterday's game, with the game finishing Dublin 0-21, Cork 0-10.
