Gardaí have appealed to GAA fans to follow public health guidelines and regulations during the All-Ireland Hurling Final weekend.
Gardaí said they have been liaising with the GAA at a national and county level to minimise the spread of Covid-19 before, during, and after the weekend's matches.
Limerick take on Waterford in the GAA Hurling All-Ireland Senior Championship, while Antrim and Kerry face off in the Joe McDonagh Cup on 13 December.
The All-Ireland Camogie Final between Galway and Kilkenny takes place on 12 December.
Gardaí have been working with licensed premises, particularly in Limerick and Waterford, to ensure their compliance with public health guidelines and regulations.
Deputy Commissioner, Policing and Security, John Twomey said: "As a life-long GAA member and former inter-county hurler, I know how much being in an All-Ireland Final means to the people of Limerick and Waterford, particularly after this difficult year."
Gardaí will have a high visibility operation this weekend with patrols focusing on the night time economy in key urban locations.
"We want this to be a great occasion for everyone, but we all must remember that Covid-19 doesn't take a day-off even for an All-Ireland Final," he added.
Gardaí and the GAA stressed the need for supporters to remember their individual and collective responsibility.
"An Garda Síochána, along with the GAA, are committed to playing our part. We are asking GAA supporters to continue to play their part by following the public health guidelines and regulations," Deputy Commissioner Twomey said.
Gardaí asked people to limit their contacts and maintain social distancing.
"If you are somewhere to watch the match and there are too many people there - leave," he said.
Deputy Commissioner Twomey said the vast majority of licensed premises have been operating in compliance with public health regulations, but action will be taken against those that are not compliant.
Elsewhere, Waterford's hurling manager and captain have appeallws to fans in the county to follow public health guidelines during and after Sunday’s game.
With the county aiming to win the senior title for the first time since 1959, there are concerns that there could be impromptu gatherings in the Waterford area, particularly if the team is successful against Limerick.
However, supporters have been asked to stick to the guidelines on Sunday to reduce the risk of Covid-19 transmission, particularly as NPHET statistics relating to the rates of diagnosed cases are "a cause of concern" in the region.
In a video clip released on behalf of the players, Waterford hurling captain Conor Prunty said the team members are "about to play the game of our lives and we are asking you to support not only us but your family, friends and community".
"Please keep yourselves and each other safe and follow the current health guidelines, so that everyone can enjoy the game," he said.

Manager Liam Cahill said all fans should be mindful of the Level 3 guidelines currently in place and to stay safe on Sunday.
"We are playing our part on the pitch and we are asking you to do the same at home for the All-Ireland Hurling Final. Please enjoy the game but bear in mind the times we are living through," Mr Cahill said.
The HSE, Waterford City and County Council and local gardaí said the "stay safe" messages are important to remember at the moment.
Similar policing measures will also be in place in Dublin and Mayo for the All-Ireland Football Final on 19 December, 2020.
Dublin face Mayo in the GAA Football All-Ireland Senior Championship, while Galway and Dublin will play in the EirGrid GAA Football All-Ireland U20 Championship.
