It's Tyrone v Kerry.
The postponed All Ireland semi final takes place in Croke Park today.
The clash was delayed due to an outbreak of Covid-19 cases among the Tyrone team.
The winners of today's semi will take on Mayo in the All Ireland final in two weeks time.
Gardaí will force pubs to close temporarily around the stadium today, if there's any anti-social behaviour.
They'll be inspecting them throughout the day.
It's after crowds gathered on the streets drinking with a lack of social distancing during the All Ireland Hurling Final last Sunday.
The justice minister said she was very concerned about the large crowds that gathered outside Croke Park for the All-Ireland hurling final last Sunday https://t.co/kXCXozr7UK

Videos of crowds around Croke Park last weekend circulated on social media, with many in the entertainment sector expressing disappointment considering their sector has been closed for so long.
“GAA exceptionalism – visible again on Sunday as fans jammed Croke Park while the live events industry was left languishing at home with platitudes about how everyone “sees the urgency” of allowing the sector to restart – is nothing new.” - @jenoconnell https://t.co/9EjYHmNKkw
