Pierce O'Learyvs Mark Chamberlain

THE BIG BANG, Pierce O’Leary, will once again be the star turn at the 3Arena in his home city of Dublin on Saturday, August 1, when he goes up against Mark Chamberlain in a first defence of his IBO world super lightweight title, live on DAZN.

The pair were originally set to deliver a potential thriller back in March before Chamberlain was forced out through illness, with O’Leary proceeding to captivate a packed house by defeating Maxi Hughes in the fifth round to become IBO world champion.

It was a first professional appearance in Dublin for the 26-year-old O’Leary (19-0, 11 KOs), and his popularity was perfectly illustrated by the ‘sold out’ signs being posted well in advance of fight night.

For southpaw Chamberlain (17-1-1, 12 KOs), from Waterlooville, this collision with O’Leary will represent his second major assignment at super lightweight, with him previously having been WBC Silver, WBA Intercontinental and IBF European champion at lightweight.

In his first title tilt at his new weight, the 27-year-old headed north to Altrincham to fight for the British and Commonwealth titles held by the undefeated Jack Rafferty. The judges couldn’t separate the pair after 12 rounds of non-stop action.
