The week before the biggest fight of Ireland’s most popular fighter’s career, the UFC has announced a fall return to Dublin.

UFC Fight Night 77 will take place Oct. 24 at 3Arena in Dublin, Ireland’s capital and largest city. The event is expected to stream on UFC Fight Pass. No fights have been announced for the card. Tickets will go on sale on Sept. 2.

“Ireland has been such an important market to the UFC and we couldn’t let a year go by without delivering another spectacular event for the fans in the capital,” stated Joe Carr, the UFC’s international vice president. “We’re looking forward to showcasing both local and international talent at the event and hopefully getting the decibel counter higher this year.”

The promotion most recently visited Dublin nearly a year ago for UFC Fight Night 46, which took place at the same venue when it was known as The O2. That event, headlined by a featherweight fight between Dublin native Conor McGregor and Diego Brandao, sold out in an hour and cemented McGregor’s status as a star.

McGregor won that fight by first-round TKO, then went on to register stoppage wins over Dustin Poirier and Dennis Siver to earn a shot at champion Jose Aldo (25-1 MMA, 7-0 UFC) next week in the UFC 189 main event in Las Vegas. That fight officially came apart on Tuesday, however, when Aldo pulled out with an injured rib. McGregor (17-2 MMA, 5-0 UFC) now meets Chad Mendes (17-2 MMA, 8-2 UFC) for an interim title.

If McGregor beat Mendes for the interim belt, the UFC would have hurdles to cross concerning whether to do a McGregor vs. Aldo unification fight at UFC Fight Night 77. That fight would be best served as a pay-per-view, leaving the UFC to deal with the time difference to the United States, as well as and Dublin’s noise curfew issues if the event was done later to accommodate a typical 10 p.m. ET pay-per-view state in the States.

There are other Irish fighters, like McGregor teammate Cathal Pendred, who could headline the show. But none of them have the draw of McGregor. Pendred fought at UFC Fight Night 46 last year in Dublin and submitted Mike King in the second round for a “Fight of the Night” bonus. The card also featured Northern Ireland’s Norman Parke, Dublin’s Neil Seery, and McGregor teammate Patrick Holohan, all of whom won their fights.

UFC Fight Night 46 at The O2 had an announced attendance of 9,500 for a live gate of $1.4 million.
