It was announced late Friday that heavyweights Deontay Wilder (pictured) and Derek Chisora will do battle at the O2 Arena in London on April 4th.  When the bruising heavyweights clash in a little over nine weeks time, it will be the 100 combined fights between Wilder and Chisora, with each guy having 50 apiece.  Wilder (44-4-1, 43 KOs), the former WBC heavyweight champion, snapped a two-fight losing streak in [a low-level comeback], stopping Tyrrell Herndon by seventh-round TKO at the end of June. Now, he looks to put together back-to-back wins against one of England's top heavyweights in the last 15 years. Chisora (36-13, 23 KOs) is [no spring chicken either but ] is on a career resurgence, having won three consecutive fights over Gerald Washington, Joe Joyce, and Otto Wallin, respectively.
