Just think for a second about this quartet of potential world heavyweight champions: WBC Corrie Sanders, WBO Lamon Brewster, IBF Andrew Golota and WBA Fres Oquendo.

Tales from the ropes - March

It's a bad dream. A bad, bad dream but it could be reality by the end of April if there are shock results in a series of fights next month.

The chaos will intensify when Riddick Bowe gets his licence back, Ike Charles Ibeabuchi gets out of prison and Mike Tyson gets his act together. Lennox Lewis is gone but the fun is only just starting!

Roy Jones Jr's decision to remain at light heavyweight for a rematch against Antonio Tarver on 15 May was a shock.

Jones toyed with John Ruiz last year to win the World Boxing Association heavyweight title and it looked like he would be able to pick his way through a mediocre, fat and bored list of heavyweights. Instead, he opted for a real fight.

The list of heavyweight championship fights in April is entertaining at best but unless the so-called champions start meeting each other the public will fall completely away.

Jones exposed the big slow men last year and showed just how easy it is for a quality boxer to lick them.

He was followed into the dismal division by James Toney and now Oscar de la Hoya is having his body checked.

The Golden Boy recently spent a long day at the University of California at Los Angeles' medical centre exploring the possibility of moving from light middle to heavyweight.

He settled on middleweight and will fight Bernard Hopkins later this year, with the winner meeting Felix Trinidad in April 2005.

Audley Harrison's return from exile in America was a success but his two greatest rivals seem to have run into brick walls career-wise.

First, Joe Mesi was dropped three times and narrowly beat former Olympic light-heavyweight champion Vassiliy Jirov, and then Dominick Guinn was outpointed by Monte Barrett.

Meanwhile, Harrison ruined Richel Hersisia to win the World Boxing Foundation's heavyweight title in front of about 4,000 people at Wembley Arena.

The belt was simply a tacky addition to a decent fight. Hersisia was just too small but he was 30-odd pounds heavier than Jirov.

Guinn fought like a fool and let Barrett, a fighter with very little ambition, beat him over 10 rounds. Harrison would beat Barrett and Jirov in the same afternoon.

Harrison will return to a British ring in Bristol on 8 May but his real test will be much later in the year and it could be against Hasim "The Rock" Rahman, who took Lennox Lewis' titles off him in South Africa in 2001 before losing a re-match.

Bristol has been in the fighting doldrums for a few years but in the last decade or so it has played host to a lot of heavyweights.

Ruiz beat Julius Francis there, Corrie Sanders defended his World Boxing Union title in the city against a dreadful loser and Frank Bruno took out Rodolfo Marin in a round on his way to beating Oliver McCall.

By the end of April England, Scotland, Wales and Ireland will know exactly how many boxers they will have at the Olympics in Athens.

In late February, over 20 boxers from the four nations tried to qualify at the European championships in Croatia but only one, Limerick's Andy Lee, secured a place.

At qualification tournaments in Bulgaria, Poland, Azerbaijan and Sweden, a steady stream of boxers will try for an elusive place at what is becoming one of sport's most difficult tournaments to reach.

Cuba receives a place at each of the 11 weights and the Greek boxing authority has been given six places but there is a chance that they will only take three or four.

"Any boxer reaching the Olympics deserves a medal," said Britain's Olympic coach, Ian Irwin.

"It is such a long and difficult road and even Audley Harrison needed a few attempts before winning gold in Sydney."
