Scott Harrison says he is ready to cut Medina down to size

The Mexican surprised the Cambuslang fighter in July to claim the title.

And Harrison this week announced that he was in the shape of his life for the 29 November return after spending weeks locked away in the Scottish Highlands.

But five-times champion Medina believes that his home-made medicine will ensure that the Scot fails to win back the title.

"I remember once when I was young I was very ill and my grandmother made me a drink to make me better," he said.

"I didn't know what it was at the time, but she later said that it was a special medicine made with the caterpillars from the jumping bean.

"I remember getting better very quickly and having lots of energy.

"When I started boxing, I used to drink the potion after I had fought to heal quicker so I could get back in the ring to earn money as we were very poor.

"I found that I could fight more often and regularly - and, in the ring, I had the energy to constantly move for 12 rounds, creating all sorts of problems for my opponents.

"I don't know what the magic substance is, but it must something special as it gives me that extra energy and buzz."

Harrison claimed he had been suffering the effects of a virus during his defeat by Medina and was violently sick shortly before the fight - a fact of which his father and trainer Peter was unaware.

The duo are leaving nothing to chance this time by taking on board a doctor to give him regular checks and dietary advice as he prepares for the re-match in Glasgow on 29 November.

And the 26-year-old Harrison said: "I am ready for the fight. I have done nine-and-a-half weeks and there will be no slip-ups this time.

"I am 100% fit and physically right and ready. This is going to be a fast fight and I'm ready to throw many punches in the fight.

Medina taunts Harrison

"Even if it goes 12 rounds, I am looking forward to bringing the title back to Scotland. I am very, very confident.

"Last time, I just wasn't 100% and I didn't get the jab or the combinations working and I was sluggish.

"But I have learned from that. That was me on a bad night. That has given me a kick up the backside.

"I know what it's like to have lost the belt, the money and my respect and I am looking forward to getting my title back."

Harrison is so determined to get his career back on track that he locked himself away from the rest of his family in the north of Scotland and put himself thorough the toughest training of his career.

Harrison's manager, Frank Warren, is also convinced the fighter is destined to become world champion again.

"This is quite a defining fight for Scott and he knows what he's got to do," he said.
