JOHN Costello believes Jamie Cox’s tune-up fight tonight is a good idea ahead of him joining the World Boxing Super Series.

The unbeaten Swindon southpaw will fight Ivan Jukic over four rounds at The O2 this evening on the undercard of Frank Buglioni’s British light-heavyweight title defence against Ricky Summers.

While tonight’s contest will not be the biggest test of Cox’s career, there will be no margin for error if he wants to fulfil his dream of fighting for a world title.

“To be honest, I’m not normally a big fan of warm up fights,” Cox’s trainer John Costello told the Advertiser. “But this one I think is a good idea.

“Jamie needs short term goals. He needs to be working towards something and by having this little tick over fight, it is a good thing.

“Since Jamie signed with Eddie (Hearn at Matchroom), he has been a changed man.

“He is a lot more disciplined and is working and living like an athlete.”

The former Walcot amateur joined Matchroom in April after leaving Queensberry Promotions.

Since joining the Hearn stable, Cox has won the WBA Continental super-middleweight title to secure a world ranking of 11 with that governing body and has secured entry to the Super Series.

“Eddie has been fantastic,” Costello said. “We’ve had two three-hour meetings with him and it has been superb for Jamie.

“It is all about Jamie, what he can do for him and his career. He believes in Jamie and that is all he has ever wanted.

“We sat down with Eddie on Monday and it is fantastic that he has managed to get Jamie into the World Boxing Super Series.”

Cox is one of three confirmed fighters in the super-middleweight category of the Super Series, joining undefeated Swede Erik Skoglund and reigning WBA Super world champion George Groves.

With five spaces to fill in the tournament, former WBA and WBC world champion Mikkel Kessler has been linked to make his return in the series.

“We are so grateful for this opportunity,” Costello added. “Eddie really argued our case to get us into the tournament and Kalle Sauerland is excited to have Jamie involved.

“Jamie’s first fight in the tournament could be for a world title and make no mistake, he will be bringing it back to Swindon.”

The draw for the Muhammad Ali Trophy will take place next Saturday in Monaco, with the four seeds picking who they would like to face from the four unseeded boxers, which includes Cox, in the quarter-finals, which are set to be held in either September or October.

The semi-finals will then be held in the new year, with the two remaining boxers fighting for the trophy next May.
