According to a report in The Sun, WBA heavyweight champion David Haye is not happy with the referee selection for his July 2 unification with WBO/IBO/IBF champ Wladimir Klitschko. Haye has reportedly protested over Chicago referee Genaro Rodriguez being picked to handle the unification showdown in Hamburg. Rodriguez was the referee for Klitschko's wins over Derrick Jeffersen, Frans Botha and Eddie Chambers, but he was also the referee when Klitschko was knocked out eight years ago in two rounds by Corrie Sanders.
