Derek Chisora was at his destructive best when he fought Sam Sexton in 2010 and knocked him out.
The pair clashed in a battle for the British and Commonwealth heavyweight titles and Chisora finished it emphatically in the ninth round.
As the two men met in the middle of the ring, Sexton was clearly exhausted and Chisora began to put the pressure on.
‘Del Boy’ was landing heavy shots in the clinch and as Sexton stumbled backwards, Chisora unleashed a barrage of wild hooks.
With Sexton on the ropes, Chisora connected with a crushing right hook that saw his opponent’s head drop and the referee quickly stepped in to wave off the fight.
And slow-motion footage shows that the power of Chisora’s punch caused Sexton’s face to completely change shape momentarily.
In his next fight, Chisora took on Tyson Fury for the first time and lost by unanimous decision, also losing his British and Commonwealth titles in the process.
Fury and Chisora would go on to have two more fights, with ‘The Gypsy King’ winning by stoppage on both occasions.
As it stands, the 39-year-old Chisora has had 47 professional bouts, with a record of 34-13, and he says he won’t retire until he has had 50 fights.
