PIERCE O’LEARY and Mark Chamberlain will finally clash THIS WEEKEND in Dublin, with the IBO super lightweight championship on the line!
The pair were meant to meet in March on the undercard of Jazza Dickens vs Anthony Cacace, but Chamberlain suffered an infection just two weeks before which led to the bout being cancelled.

Instead, O’Leary fought the experienced Maxi Hughes in front of a rampant home support in Dublin – the Irishman forced Hughes to retire on his stool after the fifth round to claim the vacant IBO title.
It was Big Bang’s first appearance in his hometown, and is now carrying huge momentum heading into the main event clash in front of his home fans.
