JAMIE Cox’s trainer John Costello has called on his fighter to fulfil his potential as he nears another comeback.

The Swindon star has had a series of false dawns over the past 12 months and his trainer is confident that the 27-year-old has the potential to make it to the top.

Following a year of inactively, which has seen the former Commonwealth light-middleweight champion losing his ranking, Cox is set to return in October in an eight-round contest.

The light-middleweight star also has an offer of a three-fight deal on the table from his old promoter Frank Warren, while there is also an option for a bout in the States.

“Once we’ve got this eight rounder done then we can start looking to fulfil Jamie’s potential,” Costello told the Advertiser. “He can go on and fight at world level - but he needs to apply himself.

“While Jamie’s been out (of the ring) he has got into the routine of having a day job - he still needs to pay the bills.

“Once we get the date finalised then he’ll be in the gym all the time, it is about making a short term sacrifice, because he can make some proper money.

“He’s got a gift, but he’s not making the most of it.

“We’re tired of talking about it, we just want to get Jamie out boxing.

“The offer from Frank is for three fights, eight round contests but it a title fight or an eliminator comes our way then Frank said he’d put Jamie in for it.

“The offer from Frank is a good deal, he’s been good as gold, it is Jamie’s decision.”

Costello is confident that his man, who hasn’t boxed since June last year, could wipe the floor with Brian Rose, who recently fought for the WBO world light-middleweight title.

“Jamie would take him out inside of five rounds and he’d only need six weeks to training to do it,” the trainer claimed.

“Jamie is head and shoulders above him.

“(British champion) Liam Smith is a good fighter, I do a bit of work with Joe Gallagher’s boys and I’d find that very hard if the two of them fought - hopefully that one won’t happen.”

Costello also says that Cox is well and truly over the hand injury that nearly put a premature end to his career.

“Jamie’s hand is better than it has ever been,” he said. “We were told that Jamie would never fight again.

“But we took him to see Mike Hayton, he looks after Amir Khan, Joe Selkirk and Tony Bellew - if you have a hand problem Mike is the man you see.

“Jamie was told by Mike that the injury was bad, but he could sort it and he did - if it wasn’t for Mike Hayton, Jamie wouldn’t be fighting.”
