The Cork puncher was stopped in the opening round of his WBA middleweight world title final eliminator in Las Vegas in September by Canadian David Lemieux on the Gannady Golovkin v Canelo Alvarez undercard.
O’Sullivan, though, is refusing to wallow and, having received little damage in the one-punch knockout loss, will be back in the ring just twelve weeks on from this defeat.
It has been confirmed tonight at the Mahon 34-year-old will box on the undercard of gym-mate Ray Moylette’s big Mayo Homecoming at the Royal Theatre in Castlebar on Friday December 7th.
What’s more, O’Sullivan will be moving down in weight and will begin his descent to the 154lbs light middleweight division on the night.
Having fully committed to training last year, the Leesider has been consistently coming in well under the 160lbs and, with the big money middleweight options now being closed off, a move downwards looks a logical choice for a fighter who still harbours major title ambitions.
The Celtic Warriors man, who is still co-promoted by Golden Boy and Murphys Boxing, is the first undercard fighter confirmed for the big Assassin Promotions bill out West.
The fight will be O’Sullivan’s first in Ireland in over four years – the last being his stunning first-round stoppage of Anthony Fitzgerald at the 3Arena in Dublin back in November 2014.
An opponent for O’Sullivan will be confirmed in due course.
