British star Chris Eubank Jr. says “Spike” O’Sullivan is in for a rough night when the pair collide in a 12-round middleweight attraction in London on Saturday night.

Eubank Jr. and O’Sullivan have been embroiled in bitter social media exchanges for three years and the Irishman has finally secured the battle he has been clamoring for. The message from Team Eubank, however, is “be careful what you wish for.”

“He has dug himself a very deep hole and he’s not going to be able to get out of it,” said Eubank, who is rated No. 9 by THE RING at 160 pounds. “No fight is simple, but he’s not the man to beat me. He’s one dimensional and he’s not got enough in his armory to beat me.

“O’Sullivan is going to get punished and I’ll be very surprised if he can go eight rounds. If he comes in and runs, he might make it late, but if he tries to use this amazing power that everyone in his team have been talking about then he’s going to walk onto big punches and get stopped.

Eubank continued, “As far as I’m concerned I am a good guy. It just so happens that the people I fight don’t seem to like me very much. That means I’m getting into these so-called grudge matches, but to be honest, I don’t know ‘Spike’ so I cannot have a grudge against him. All I know is that he’s obsessed with me.”

The winner will be the mandatory challenger for Daniel Jacobs, who holds a version of the WBA middleweight title which is not recognized by THE RING.
