A number of pubs across Sydney have banned the Floyd Mayweather and Conor McGregor 'fight of the century' from being shown this weekend because of concerns about drunken violence.
he Sunday Telegraph reports that publicans fear Irish backpackers will cause trouble if McGregor loses the billion-dollar fight.
Licensing police have warned pub-owners to only serve alcohol in plastic cups and not to serve 'shots'.
Normal security will be trebled at most venues that show the fight, while police confirmed extra officers will be on duty.
"It's primarily the high risk of antisocial and unacceptable behaviour from the McGregor supporters," publican Bob Tate said.
"They are a very passionate group that wear their heart on their sleeve.
"The majority of long-term Irish residents are great fun and great people but problems arise with the transient backpacker Irish traveller who does not conform to our responsible service of alcohol requirements and goes way too far, then disappears into the night to travel to their next destination.
"History and undeniable evidence shows me the likelihood of problems during or after the event is substantial.
"Economically, unless you are an extremely big venue you just cannot sell enough food and beverage to cover costs of extra security."
The Empire Hotel in Kings Cross, a spot popular with Irish backpackers, is also not showing the fight.
