Klitschko vs Pulev: Live streaming results and round by round coverage

Today at 4:45 pm EST on HBO, Eurosport (UK), and RTL (Germany), Wladimir Klitschko returns to the ring to take on unbeaten top contender Kubrat Pulev at the O2 World Arena in Hamburg, with the WBA, WBO, and IBF world heavyweight titles on the line.

Klitschko (62-3, 52 KO) has dominated the heavyweight division since regaining a world title (IBF) against Chris Byrd in April 2006, making 16 straight defenses of that title, and along the way also picking up the WBO (Sultan Ibragimov, Feb. 2008) and WBA (David Haye, July 2011) titles to add to his collection.

Pulev (20-0, 11 KO) is a 33-year-old Bulgarian who has a lot going for him. He's not dramatically smaller than Klitschko, as he's about 6'4" to Wlad's 6'6", and weighed a shade more than Klitschko yesterday. He's physically strong and probably won't be so easily pushed around as some others have been.

But he also has a fine amateur pedigree, which really sets him apart from many of Klitschko's challengers over the years. He won gold at the 2004 EU Amateur Championships and 2008 European Amateurs, as well as silver at the 2005 EU Amateurs, and bronze at the 2005 World Amateurs and 2006 European Amateurs. "The Cobra" is a legitimate contender, and though he may or may not fare any better than anyone else has -- i.e. not well -- he's not a complete pushover on paper, either.
