The Battle for the Planet - Saturday 19th April 2008, Las Vegas, USA. He stepped up a weight, off a plane, through the ropes and into boxing legend. 707...no, not the super jet but the number of punches thrown by "Super Joe" in a night of high octane fighting action. Calzaghe, in his first ever fight at light heavyweight and his first in Las Vegas took on the fearsome 'Executioner', the powerful fighter and former champion that feared no man. Within seconds of the opening round, Hopkins showed his skill and strength when he put Joe down with a devastating short, straight right hand. From that moment on Calzaghe demonstrated why he is Britain's most successful post-war champion with unrelenting speed, energy and determination. Hopkins tried every trick in the book from fouling and feigning injury to holding on but it simply wasn't enough. As every stinging round passed, Joe took more and more control of this brutal encounter. After 12 punishing rounds the all American judging panel, split in their decision, awarded the bout to Calzaghe - an incredible victory. The super middleweight WBC, WBA and WBO Champion is now the world's No.1 light heavyweight and this exclusive video shows every second of the action.
