Warren, after lengthy negotiations with O’Sullivan’s manager, Paschal Collins, wants the Corkman to target the Commonwealth light middleweight title.
“Spike was actually born in England which makes him eligible to box for the Commonwealth title,” Collins said. “That is now our target and I could see it happening after two or three fights.”
O’Sullivan met Warren in London last week along with Paschal Collins and his brother, Steve, the unbeaten WBO world super middleweight champion.
“I have the contract in my hand as we speak,” O’Sullivan said. “It is a three-year contract. I will have a minimum of five fights per year and I will fight for the Commonwealth title sooner rather than later.”
O’Sullivan, who holds the Irish middleweight title, will box in tandem with the talented Dubliner, Stephen Ormond, who is also managed by Collins.
“Himself and Stephen Ormond will both be making their debuts in Glasgow on September 4 and they will be fighting for Frank Warren for the next three years,” Collins confirmed.
“After Spike beat Sylvain Touzet in Cork there was talk about him defending his Irish middleweight title against Anthony Fitzgerald but nobody ever talked to me about it.
“All Don (O’Leary) has to do is pick up the phone and we will certainly discuss it but there is no question of him fighting Anthony Fitzgerald right now.
“Frank Warren wants to promote a couple of shows in Ireland and I would see Spike and Stephen Ormond headlining those shows.”
Paschal Collins has been involved with O’Sullivan since his winning debut against Peter Dunne in Cork in January 2008 and, since then, the Corkman has chalked up another 10 victories including a points win over Belfast man, Ciaran Healy, for the vacant Irish middleweight title.
“Obviously this is the opportunity I have been waiting for,” O’Sullivan said. “I knew our meeting with Frank Warren in London went very well but you are never sure until you have that contract and now that I have it in my hand I am pretty excited about it.”
