Two of boxing's premiere heavyweights will collide in Mannheim, Germany when IBF Heavyweight Champion Chris Byrd (39-2-1, 20KO's) steps into the ring against former heavyweight champion and top contender Wladimir Klitschko (45-3, 40KO's) on Saturday night April 22nd in Mannheim, Germany. This is the second meeting between these two warriors. The first meeting took place over five years ago in October of 2000 when Klitschko defended his WBO Heavyweight Title with a 12-round unanimous decision victory in a fight that also took place in Germany. Since capturing the once vacant IBF title against Evander Holyfield, Byrd has successfully defended his title four times; most recently winning a unanimous decision victory over DaVarryl Williamson on October 1st, 2005. In Klitschko's last fight, he cemented his place among the top heavyweights and put himself in position for a title shot with a unanimous decision victory over previously unbeaten Samuel Peter in Atlantic City on September 24th. The Byrd-Klitschko IBF/IBO Heavyweight Championship Bout will be aired on HBO World Championship Boxing on Saturday Night April 22nd.
