EDDIE Hearn has promised to put his money where his mouth is to kick-start Jamie Cox’s career.

The head of Matchroom Boxing was delighted to complete the signing of the Swindon southpaw.

With Cox seeing his career stagnate over the past year before his release by Queensberry Promotions, Hearn knows that he has to raise the profile of the ex-Commonwealth light-middleweight champion, who is undefeated in 21 fights.

Now campaigning in the super-middleweight division, and under the Matchroom banner, Cox could see his first outing come against newly-crowned British champion Rocky Fielding, who is also under a promotional agreement with Hearn, after the Boxing Board of Control mandated the fight.

“I’m delighted (that I’ve signed Cox),” Hearn told iFLtv.co.uk. “I can say it now, he was always the one I looked at and thought ‘he’s dangerous, he is. He is going to cause some problems for our boys and the division’ and now we have got him.

“Twenty-one and 0, ready to go. He is the mandatory (for the British title) which is a fight I think he’d like to jump into straightaway.”

Since February 2015, Cox has had only had four fights, with three them not going beyond the opening round.

The 2006 Commonwealth Games gold medallist was last out in October when he took the decision in an ugly war against Martin Fidel Rios.

With fights not easy to come by, Hearn knows that he is going to have to invest to get his new signing fighting on a regular basis.

“Jamie wants to get out as soon as possible,” Hearn added.

“We have got a lot of shows coming up. We have got Birmingham (May 13), the Kell Brook card (May 27), the O2 on June 3, another one June 10 (in Belfast) and another on July 1.

“He needs to box twice before the first week of July and twice again between September and December.

“I said to him when we sat down ‘you’re a nightmare, your profile is not that high and you’re dangerous, so why on earth would anyone want to fight you?’ “He is going to be very, very busy, but we have to do it right, he was ready to go at the weekend.

“But we have to do it right, not make mistakes going in looking sloppy when we aren’t prepared.

“He has got a whole career ahead of him – I think that he has got six years left in the game.

“We have some big shows coming up, some big pay per view cards where we have got the budget to bring over the big names. I’m willing to invest to get these names over.”
