After a troubled youth that saw him spend several spells in prison, Francis turned pro in 1993 at the late age of 28 with a five-round knockout of Graham Arnold. He put together six wins (3 by knockout), including two in the US, before being matched, somewhat prematurely, with future world heavyweight champion John Ruiz. Francis was stopped in 4 rounds by body shots.
In 1995 Francis won Southern Area title fights against Damien Caesar and Keith Fletcher. However, he squandered a big opportunity in an eliminator, when far ahead on points after nine rounds, hard hitting Scott Welch came from behind to drop him three times and stop him in 10. After this fight, Welch would go on to win the British title and challenge for a world title, while Francis was dropped by his team and relegated to journeyman status.
Later in 1995, he took a fight in Russia and was outpointed by local Nikolai Kulpin and, in London, lost a debatable decision by half a point to veteran Michael Murray.
Francis showed marked improvement in 1996, knocking out ex-victim Caesar in the first round to regain his Southern Area title, outpointing Michael Holden, and scoring the biggest win of his career to date as he took on hard hitting "Big Bad" James Oyebola and destroyed the giant Nigerian in 5 one sided rounds.
The big win over Oyebola got Francis a February 1997 shot at Zeljko Mavrovic for his European title, on the champion's home turf of Austria. Francis "stole" Mavrovic's bizarre mohawk haircut for the fight and even dyed it blonde. In the fight itself, Francis strangely took a knee from body shots in the 8th and watched the ref wave the fight off. Mavrovic would go on to lose on points to Lennox Lewis in a World title challenge, a fight that Lewis would say in 2006 was "the hardest of my career".
In June, Francis was back, outpointing the hard hitting Zambian Joseph Chingangu in London for the Commonwealth title, and in September retained his Commonwealth title and won the vacant British title with a 6th-round knockout of Garry Delaney in Northern Ireland.
His manager Frank Maloney was unsuccessful in attempting to move Francis up in 1998, as he was outpointed in Germany by local icon Axel Schulz in a European title eliminator, and a second visit to German shores saw him decked three times and stopped in the second round by giant Ukrainian Vitali Klitschko. Klitschko would go on to win the World Heavyweight title.
In 1999, Francis was back and enjoyed the best form of his career. In January, he defended his British and Commonwealth titles against the flamboyant, hard hitting and highly rated prospect Pele Reid, who was 13-0 (13 knockouts) and favoured to beat Francis. Francis took Reid apart in 3 one-sided rounds.
In April, he was again the underdog as he defended against another highly rated prospect, this time Frank Warren's undefeated Danny Williams, who was 15-0 (12 knockouts). Francis used all his smarts to widely outpoint the "Brixton Bomber". This win gave Francis the coveted Lonsdale Belt outright as he had now won three British title fights.
In June, he enjoyed the sweetest victory of his career as he outpointed former conqueror Scott Welch who was 22-3 (17 knockouts). He would vacate his Commonwealth title later in the year to set up the biggest fight of his career. At the age of 35, Francis got a shot at visiting iconic ex-champ Mike Tyson, in Manchester in January 2000. Francis was decked five times and lost in two rounds, although enjoyed the biggest payday of his career (around £350,000). The certainty of his defeat can be gauged by the fact that The Mirror, a national newspaper in the UK, had paid £20,000 for an advert on the soles of Francis's shoes. Less than two months later, a disinterested Francis was back in the ring and lost his British title on a close decision to Michael Holden, whom he had already beaten. Holden would later vacate the title due to injury.
In 2001, Francis returned to complete his trilogy with Holden, outpointing him over 12 rounds, and setting up a July rematch with Danny Williams, who was now #1 in the UK, world rated, and held the British and Commonwealth titles. Francis failed to repeat his earlier win, losing in the 4th round due to a swollen eye.
He would resurface in September 2002 in Denmark, scoring an upset over undefeated Steffen Nielsen, who he knocked out in 6. This earned him a European title shot in Germany against the Turk Sinan Samil Sam, who had just crushed Danny Williams in 6 rounds. Francis appeared to make little effort, quitting in the 7th round from body shots.
In early 2009, he began a new career with Fightfit Training a (UK based fitness training company) as a Personal trainer/Boxing coach teaching city professionals the art of Boxing.
Francis was now 38 years old and with a respectable record of 23-10-1 (12 knockouts).
He would mix in with high class company in the UK, Germany, Russia, and other locations, but he would not win another fight. The most notable fights were a November 2003 second-round KO loss to future champ Oleg Maskaev (26-5), a February 2004 decision loss to fast rising Matt Skelton (11-0), and a May 2004 decision loss to Olympic Champion Audley Harrison (15-0).
Francis appeared to have reached the end of the road in May 2006, when he was outpointed over 4 rounds by unknown Scott Lansdowne. He was 41 years old and weighed well over 19 stone. Having lost 14 fights in a row, his record now stood at 23-24-1 (12 knockouts).
Overall, Francis has won four British Heavyweight title fights and five Commonwealth title fights, as well as two challenges for the European title and he has fought four former or future World champions, besides owning his very own much heralded Lonsdale belt.
In the summer of 2007, Francis announced that at Cage Rage 23: Unbelievable on 22 September 2007 he would be making his mixed martial arts debut against Gary Turner. Francis stated that he expected the move to mixed martial arts to be comfortable for him as he was already a good kickboxer before he took up boxing. His opponent Gary Turner was previously beaten by Matt Skelton, one of Francis's own conquerors, in a K-1 tournament in 2000.
Francis lost his MMA bout against Turner by submission (Strikes) at 2:15 in Round 2.
In 2012, Francis starred in the stage play Ring Envy, a modern version of Shakespeare's Othello in London, his performance earning praise from the likes of Sylvia Sims.
