Looks like a May 29 clash of giants between 6′7 WBC heavyweight champion Vitali Klitschko and 7-foot former WBA heavyweight champion Nikolai Valuev is a no-go as a deadline looms to reserve the fight venue. The Valuev camp, specifically Don King, is holding out for $4 million, while the Klitschko camp is standing firm at $2 million. Klitschko representative Shelly Finkel told BILD “[Valuev] can accept, otherwise we’ll box a different opponent.”
