There is no danger Danny Butler will allow success to go to his head should he become Prizefighter champion in London's East End tonight. His family simply wouldn't allow it.

Bristol's rising boxing star may be destined for a glittering career in the ring, but he will never allow himself to forget the school of hard knocks which has helped shape his nearest and dearest.

If those at ringside at the York Hall in Bethnal Green tonight think boxing is tough, they should take time out to meet Butler's brothers.

Elder siblings Martin and Adam have served Queen and country in some of the world's most dangerous theatres of war and Danny, the baby of the family, has the utmost respect for both of them.

"They are the real heroes, not me," says the 21-year-old Bristolian, who will be roared on by a travelling contingent of more than 100 friends and family.

"Boxing is a tough game, but it's only a sport. My brothers have both served in Afghanistan and that's the real world.

"If I ever feel a bit frightened before a fight, I only have to think of what they go through every day to put things in their true perspective.

"I have to deal with someone trying to knock my head off. They have to deal with people shooting at them and trying to kill them.

"I know what they've both been through and I admire them so much.

"They're an inspiration to me and I've always looked up to them. Now I want to make my brothers proud of me."

Martin, 28, serves in the Royal Logistic Corp and is currently based in Northern Ireland. But 24-year-old Adam will take time out from his role as a bomb disposal expert with the Royal Engineers to cheer his younger brother on at ringside tonight.

"I'd love to win the title in front of Adam," added Butler, who has been installed as joint second favourite by bookmakers to win the Prizefighter Series.

"I've sold about 100 tickets and there's going to be a lot of support for me. Hopefully, I can give them something to shout about and make the journey from Bristol worthwhile for them all." Butler meets Newport veteran Paul Samuels in the first round and has promised to make a donation to the Help for Heroes charity which supports servicemen and women who have been injured in action if he wins the £25,000 first prize.

He said: "It's a great charity which helps people who deserve better. People don't realise how little money injured veterans have to live off and I'd love to be able to do my bit to help."

Prizefighters will be screened live on Sky Sports tonight, starting at 9pm.
