David Haye and Dereck Chisora have never before faced off in the ring, but Saturday's controversial fight is borne of their mutual animosity.
Trouble brewing —
Former WBA heavyweight champion Haye confronted Chisora at a press conference following his fellow British boxer's defeat by Vitali Klitschko in February.
Munich mess —
The Haye and Chisora teams then got involved in a violent brawl. Haye's manager Adam Booth was left with a bloodied face after being allegedly struck with a bottle.
A slap in the face —
Chisora had sparked controversy when he slapped Klitschko at the weigh-in ahead of their fight, and spat water at the Ukrainian's fellow world champion brother Wladimir. He subsequently lost his boxing license.
Women in the ring —
With the men's side of the sport receiving so much negative press, Britain's Lisa Jane Whiteside (left) and Poland's Sandra Kruk will be hoping to show the world what women can do at the Olympic Games this summer. Here are a few of the ones to watch...
'Magnificent Mary' —
Mary Kom is one of the finest female boxers of her generation. She is the only woman to win a medal at all six Amateur World Championships, taking home the gold on five occasions. The 29-year-old is India's only qualifier for the Olympics and is also the IBA's Ambassador for Women's Boxing. In 2010 she was voted Indian Sportswoman of the Year.
American ambition —
At only 17 years of age, Clarissa Shields has already won 27 bouts, with 14 knockout wins to her name and only one loss. The U.S. middleweight has won two Junior Olympic championships and will be looking to add to that at London 2012.
Britain's big hope —
Savannah Marshall is Britain's strongest candidate for boxing gold on home canvas. In May the middleweight became the first Britsh woman to win a world title, overcoming a bloodied nose to beat Azerbaijan's Elena Vystropova on her 21st birthday.
Irish invincible —
Ireland's European and world champion Katie Taylor has won a total of 13 gold medals across three different federations, all at the 60 kg weight class. She has also represented the Republic of Ireland at international level in football, and might be recognized by some after starring in a recent Lucozade Sport advertisement.
UK pioneer —
Ranked third in the world in the flyweight (51kg) division, Nicola Adams has been a pioneering figure for British women in the sport. In 2001 she became the first female boxer to ever represent England and in 2007 she became the first Briton to win a medal, with bantamweight silver at the European Championships and is now the continental flyweight champion.
