Dereck Chisora hasn’t knocked out any of his last four opponents, but the London-based boxer from Zimbabwe believes that streak will end Saturday.

Chisora (15-3, 9 KOs) predicted that he’ll knock out David Haye (25-2, 23 KOs) when these brash British heavyweights meet at West Ham Football Club’s Boleyn Ground at Upton Park in London (EPIX; 4:30 p.m. EDT/1:30 p.m. PDT).

“Trust me, he’s getting knocked out,” Chisora said to promote their 12-round grudge match. “He said he’s going to knock me out in round three. He’s going down in round seven. Lucky seven.”

Chisora showed a granite chin during his 12-round unanimous decision defeat to WBC champion Vitali Klitschko (44-2, 40 KOs) on Feb. 18 in Munich, Germany, where Chisora’s controversial post-bout brawl with Haye helped lead to this fight materializing. Each of Chisora’s three losses have gone 12 rounds and other than a brutal body blow Klitschko landed in the third round of their fight, Chisora cannot remember being truly hurt in a fight since he out-pointed Welsh heavyweight Darren Morgan (5-5, 3 KOs) in a four-round bout, just the third of Chisora’s pro career.

“The guy, Darren Morgan, hit me so hard I didn’t realize where I was,” Chisora said of their October 2007 fight in London. “I came back to the corner and my trainer goes to me, ‘What’s wrong?’ … It took me about two minutes to come back [from that punch].”

The 28-year-old Chisora cannot envision the heavy-handed Haye hurting him that way when they go at it.

“David Haye’s a cruiserweight,” Chisora said. “He can only hurt you if he sees an opportunity, but we’re not going to give him an opportunity to hit me.”

The 31-year-old Haye has lost once by knockout during his 9½-year pro career.

England’s Carl Thompson (34-6, 25 KOs), who was 40 when they fought for the IBO cruiserweight championship, stopped Haye in the fifth round of their September 2004 fight in London. Thompson dropped Haye with a right hand in the fifth round, but referee Terry O’Connor stopped that fight while Haye was on his feet.
