Moments ago, Vitali Klitschko's advisor Shelly Finkel informed Boxingtalk.com that a sprained ligament in his right knew has forced the WBC  heavyweight champion to postpone his eagerly anticipated title defense against Hasim Rahman. Finkel told Boxingtalk Klitschko was unable to move comfortably with the brace on, and obviously he doesn't want to face Rahman unless he's at his best. This is the fourth postponement of this bout which was originally scheduled for April 30, then June 18, then July 23 then November 12. As of now no replacement dates have been soldified. We will continue to keep you updated. Remember where you heard it first! (8:40 PM EST)
