The pair will fight on the undercard of Matthew Macklin’s bout with Sebastian Heiland in Dublin’s 3 Arena.
It will be O’Sullivan’s first high-profile fight since losing the WBOinternational middleweight bout to Billy Joe Saunders on a unanimous decision, having fought only once, against journeyman Jose Medina in Boston, in the 15 months since.
However, O’Sullivan now believes the roadmap towards a world title fight has been put in place.
“The next 12 months will be very important and I hope to be world champion by the end of it. I’ve been talking to [promoter] Eddie Hearn and I think it’s more of a possibility than ever.
“This fight is going to be an eliminator for a world title fight so in three fights’ time I could be fighting for a world title. So when I win this one, I’ll be fighting a world title eliminator in February and then maybe in the summer again.”
O’Sullivan accounts most of his recent inactivity to bad luck; with a series of injuries, opponents ducking him and the cancellation of his initial fight with Fitzgerald, due to the shooting of Jamie Moore, preventing him from taking to the ring.
“A lot of guys out there are protecting their undefeated records and there’s politics involved in it too, so it’s been very frustrating.”
O’Sullivan was keen to take on the unbeaten Chris Eubank Jr. in the aftermath of the Fitzgerald postponement; however it was a fight he was not able to make happen.
“Once I signed for the Anthony Fitzgerald fight, Chris Eubank said he wanted to fight me and that he was going to smash me up. Then my fight fell through and I approached Eubank, called his bluff really, and said to him, ‘look, you were looking to fight me when I signed to fight Anthony Fitzgerald and now that fight is off; let’s have the fight’. But I never heard one thing from him.
“I flew over to London as well. I went to Frank Warren’s office and said it to him. But it was just one excuse after another really.”
O’Sullivan was speaking prior to the official announcement of the rematch at the launch of ‘The Fight for Autism’, a white-collar boxing event which will be held in the Savoy, Cork on November 29. The fight night is in aid of My Canine Companion, a non-government funded charity which provides highly trained service dogs to children with disabilities, particularly those with autism.
