IBF and WBO Heavyweight Champion Wladimir Klitschko of Ukraine has defended his titles with a 12th-round knockout of U.S. boxer Eddie Chambers.
His title defense bout took place on Saturday night in Germany's Dusseldorf at the ESPRIT Arena, which is a 51,000-seat football stadium.
The American offered stiff resistance to the Ukrainian boxing legend throughout the bout but succumbed to Klitschko's heavy punches 20 seconds before the end of the final round.
Klitschko held his previous title defense bout also at a football stadium, when he defeated Uzbekistan's Ruslan 'the White Tyson' Chagaev in front of a crowd of 61,000 at the Schalke 04 stadium in Germany last June.
