CLACTON super-middleweight Justin Johnson says he is going to keep fighting to change his son's life.

Johnson has had a tough start to his career in the professional ring, with one win and a draw from his first three fights.

He had been scheduled to face Richard Harrison, at York Hall, in Bethnal Green, on July 30.

A kidney infection means he has been forced to withdraw from the fight, but it has already been rescheduled for October 1.

And win or lose in the autumn, he is set to carry on fighting.

Johnson is raising money for five-year-old son Leon, who has cerebral palsy and is paralysed from the waist down.

"Leon is getting stronger through physio and I'm hoping to raise enough money for an operation that can help him walk," said the 32-year-old.

"I'm hoping boxing might change things for him.

"I've had a tough start to my boxing career but if I give up, Leon might give up trying to walk.

"I'm going to give it at least another couple of years.

"I'm hoping to get a few wins and get a shot at a British Challenge belt next year.

"I know what my capabilities are. I spar good lads in the gym."

Johnson was outpointed by Tariq Rashid in his last fight and says that has convinced him his future is at super-middleweight, rather than light heavyweight.

He said: "Technically, he wasn't the best, but he had the weight and the size on me and I got tired.

"I was picking him off, but he kept coming forward wind-milling.

"I took a lot of his shots on my gloves, but the referee must have given him rounds for being aggressive.

"I feel much more confident and comfortable at super-middleweight.

"That's my weight."

Johnson says he's still confident - despite a tough introduction to professional boxing.

He said: "I go into every fight confident and if I stay confident and focused, I will pick up a few wins.

"But in boxing, if you put one foot wrong, you can end up losing."
