"&lt;p&gt;&lt;/p&gt;&lt;p&gt;\n\n&lt;/p&gt;&lt;p&gt;Representatives for IBF/WBO heavyweight champion Wladimir Klitschko and WBA champion David Haye are close to an agreement to match Haye and Klitschko in a unification fight, an industry source told SI.com. The fight will be held in Germany in either June or July.&lt;/p&gt;&lt;p&gt;On Friday, Klitschko withdrew from next month's scheduled title defense against Dereck Chisora, citing an abdominal injury. The decision to withdraw clears the way for a summer bout with Haye, who reportedly was unhappy with Klitschko's insistence on taking the fight with Chisora in the first place.&lt;/p&gt;&lt;p&gt;Klitschko, however, has steadfastly refused to tie his future to Haye due to Haye's unpredictability. In June 2009, Haye pulled out of a signed fight with Klitschko less than three weeks before the date, citing a back injury. Klitschko eventually replaced Haye with former champion Ruslan Chagaev. Klitschko beat Chagaev in a lopsided, nine-round technical decision.&lt;/p&gt;&lt;p&gt;Since then Klitschko has doggedly pursued a fight with Haye. He has called him out in the press and produced a YouTube video daring Haye to get in the ring with him.&lt;/p&gt;&lt;p&gt;A Klitschko-Haye fight would be the biggest fight in the heavyweight division since Klitschko's brother, Vitali, lost to Lennox Lewis in 2003. The fight would draw a crowd of more than 60,000 at a German soccer stadium and generate interest from televisions outlets in the U.S., where it would likely be shown on HBO, and abroad.&lt;/p&gt;"^^<http://www.w3.org/2001/XMLSchema#string>
