Haye victorious in Chisora grudge match, Amir Khan knocked out by Danny Garcia

David Haye knocked out Dereck Chisora in the fifth round of their all-British heavyweight grudge fight at Upton Park on Saturday.

Five months after they brawled in Munich at a news conference, Haye put Chisora down for good with a left hook, but Haye (26-2, 24 KOs) was coming under severe pressure until the knockout in an exciting fight before 30,000 spectators.

The fight panned out as expected. Former world cruiserweight and heavyweight champ Haye had speed and a harder punch, while Chisora (15-4, 9 KO) used his extra 37 pounds (17 kilograms) to crowd Haye and land threatening blows.

They continued hitting after the bell in the second and third rounds, and Chisora avoided trouble in the fourth when Haye let up. In the decisive round, Chisora survived an eight count but another Haye left hook dropped Chisora and referee Luis Pabon waved it all over.

No world titles were at stake in the scheduled 10-rounder which was sanctioned by the Luxembourg Boxing Federation because the British Boxing Board of Control wouldn't license either fighter after their shameful antics in Munich.

The pair traded insults and blows after Chisora lost to WBC champion Vitali Klitschko on Feb. 19 and then taunted Haye during the post-match news conference over the loss of his world title.

The BBBC stripped Chisora of his license after the incident. Haye relinquished his license last year when he retired following the loss of his WBA title to Wladimir Klitschko, Vitali's brother.

The mutual dislike between Hayes and Chisora helped to attract a large crowd in London — more than attended the Lennox Lewis-Frank Bruno heavyweight title bout in 1993.

Meanwhile, American Danny Garcia knocked out Britain's Amir Khan in the fourth round to add the WBA light-welterweight crown to his WBC super-lightweight title in Las Vegas on Saturday.

Khan, 26-3 (18 KOs), looked the superior fighter early on, showing vastly superior hand speed as he landed right hands behind a long jab and opened up a cut on Garcia's eye with a left hook.

Garcia's defense remained tight and effective, however, and in the third round began throwing thudding shots to Khan's body and near the end of the round he landed a powerful counter left hook that dropped Khan hard on to his back.

The Briton struggled to his feet, but was on shaky legs as the bell rang.

Garcia dropped Khan again at the start of the fourth with a right hand and as he retreated, Garcia gave chase, launching huge punches as he did so.

A left hand put Khan down once more, and although he beat the count, referee Kenny Bayless stopped the fight though the Briton thought the stoppage may have been premature.

"I was a little surprised the ref stopped it," he said. "I thought he was going to let us continue. My mind was clear, and I thought my legs were okay.

"(But) it wasn't my night. I respect Danny. He was countering very well against me. I got a little complacent and he took advantage and he caught me."

Garcia said he had felt the Briton had underestimated him.

"We knew Khan was going to come out fast because he thought I had no power," said Garcia who improved to 24-0 (15 KOs).

"But I waited and stepped up and used the speed and power I have. And it worked."
