Dereck Chisora is aiming to make quick work of Kevin Johnson at the Copper Box Arena on Saturday to send a warning to his rival Tyson Fury.

Chisora, from Hampstead Garden Suburb, defends his WBO/WBA International Heavyweight titles against the tough American Johnson, who took big-punching Fury the distance in December 2012 – and he knows he needs a strong showing to stay on track for this summer’s grudge match with the Mancunian.

Undefeated Fury took Chisora’s British and Commonwealth titles as well as his unbeaten record in July 2011, and he features as the chief support act on the undercard this Saturday, with a 10-rounder against American Joey Abell.

‘Del Boy’ Chisora is now putting the final touches on his seven-week training camp with trainer Don Charles, and he knows he will have to be at his best against the veteran Johnson.

As well as Fury, Johnson has taken the heavy shots of former WBC king Vitali Klitschko, going the distance against the Ukrainian in May 2009.

Chisora said: “Johnson’s a good strong American fighter with a good reputation – just what I need to make me perform to my best.

“He’s a tough boy, he’s taken Fury and Klitschko the distance, and if I can become the first man to stop him then it sends a big message to Fury and the rest of the heavyweights out there.

“The focus is on Johnson for this fight, Fury will be there in the background and he’s next, but I’m going out there to put everything on the line and take him out.”
