CHRIS EUBANK junior has revealed he has stayed in shape for his short notice comeback fight thanks to the “kick up the a**e” of training with Floyd Mayweather Senior.

Eubank Jr is back under the watchful eye of long-term trainer and Team Eubank overseer Ronnie Davies in Sussex ahead of flying out to Saudi Arabia tomorrow in preparation for Friday’s non-title scrap with JJ McDonagh.

It will be Eubank Jr’s first fight since losing to George Groves last February in the World Boxing Super Series semi-finals.

Groves tops the bill in Jeddah against fellow Brit Callum Smith while Eubank has been slotted in as the main support against Irishman McDonagh.

The fight was only agreed a matter of weeks ago but Eubank Jr says he was keeping busy in the gyms of Las Vegas during an extended stay in the States.

And the Brighton super-middleweight linked up again with Mayweather Senior during the two months he was out there.

The 29-year-old admits he did not get the amount of sparring he wanted with no firm fight on the horizon but reckons Mayweather’s sessions helped keep him on his toes.

Eubank Jr told The Argus: “I was training every day.

“I definitely had a bit of fun out there at the beginning but as it got closer to this date, although I didn’t have an official fight or opponent, I was in the gym.

“I was learning and training with Floyd Mayweather Senior.

“I didn’t get as many rounds in as I wanted to but it’s one of those things where the guys have got to be in the gym.

“Sometimes the guys have just fought or are not around.

“But I got enough sparring in for this fight.”

And he revealed the work with Mayweather, father of Floyd Jr, stopped him losing focus when the bright lights beckoned in the party capital of the world.

He said: “The training with Floyd — that type of pad work and speed, it really gives you a nice kick up the a**e when you’re thinking about maybe going out to a club or to a pool party.

“When you know you have half an hour with Floyd — it’s crazy.

“He is 64 years old and the speed with which he puts me through combinations is absolutely crazy.

“I can only hope to be as sharp as him at his age.

“It’s always great working with the Money team.”

Eubank has said many times he wants to fight in the USA and admits Vegas is special to him.

He said: “It’s my home away from home. I spent a lot of time there as a teenager and started my amateur career there in the Golden Gloves and the Nationals.

“It’s a place which is close to my heart and I’d love to fight out there.”

Eubank Jr admitted exclusively in The Argus last week he has something”tasty” lined up for the end of the year.

And he suggested his wish to fight over the pond may not be that far away despite a showdown in Britain with James DeGale being favourite for the immediate future as long as they both get through comeback fights this weekend.

He said: “It has to happen one day, it could happen at the end of this year. You’ll have to wait and see.”
