In 2003, Vitali Klitschko and Lennox Lewis finally took to the ring to fight for the title as the best heavyweight boxer on the planet.

Lewis had beaten Mike Tyson a year earlier, whilst Klitschko was well on his way to the very pinnacle of the sport.

The bout was dubbed as ‘The Clash of the Titans’ – and rather than settling scores, the fight generated more questions than answers.

Both fighters landed several huge punches, yet with a Lewis punch opening a deep cut above Klitschko’s eye early on, the fight was eventually stopped to complete a controversial TKO win for Lewis.

The crowd were far from satisfied with the stoppage, and Klitschko was so keen to avenge the defeat that he launched a campaign demanding a rematch.

Lewis retired to end hopes of another fight, and a sense of unfinished business has lingered.

It came as a surprise then, when an announcement was made in July that there would be an exhibition rematch at the WBC convention in Kiev.

It has now emerged that rather than throwing punches at one another, the two legends will be shunning the boxing gloves for a battle on the chessboard.

The fighters will be playing a game of chess inside a boxing ring at the Kiev event, with Lewis claiming that both are “too old” to be boxing.

“We are going to play a chess match inside a boxing ring,” Lewis said.

“We are too old now to be pulling on the gloves again. It will be interesting for us to pit our wits against each other rather than our fists,”

Vitali regularly plays against his brother, as well as attending chess events in his free time. This hasn’t stopped Lewis saying that he will ‘definitely’ win.

Whilst nice to see both enjoying retirement, we’d guess that this one probably wouldn’t do too well on pay-per-view.
