Queensberry set for Irish return with Pierce O’Leary in the headline role
Apr 20, 2026 • 2:18 PM ET
Queensberry Promotions/Leigh DawneyHot on the heels of their last successful foray into Ireland, Queensberry Promotions returns to Dublin on August 1.
They will be back at the 3Arena where, on March 14, Anthony Cacace defeated Jazza Dickens via decision in front of a sold-out crowd on a bill that saw the popular junior welterweight Pierce “Big Bang” O’Leary impress against veteran Maxi Hughes.
This time, the 19-0 (11 KOs) O’Leary, 26, will box as the headliner on a show that includes Brian Peters-managed heavyweight prospect Adam Olaniyan, who got off the mark as a professional on the last Dublin bill, 14-0 lightweight Steven Cairns, who stopped Arnie Dawson in nine rounds, and Irish veteran Jono Carroll.
There’s also a spot on the show for 1-0 Dublin hotshot Bobbi Flood, who caught the eye with a 68-second blitzing of experienced Hungarian Bela Istvan Orban, dropping him twice.
Irish heavyweight prospect Olaniyan is also out this weekend, on Queensberry’s Paris bill, against Cameroon-born Andre Youmbi Oyen.
O'Leary's opponent will likely be announced this week.
