Over 80,000 people will attend Croke Park on September 5th for Katie Taylor's final fight.
Tickets for the fight are now sold out after they went on general sale on Ticketmaster at 9am this morning.
The Bray fighter will face off against France's undefeated Flora Pili, in her effort to become the three time undisputed champion of the world.
Former World Champion Barry McGuigan, says "she's [Katie's] become so popular, she's won everything as a professional fighter, she's extremely talented, nobody will have any issues with her stealing that title."
It will be the first time a professional boxing match has been staged at the historic Gaelic grounds since the late Muhammad Ali famously fought Detroit heavyweight Alvin ‘Blue' Lewis back in 1972.
