American Danny Batchelder is now off as Alexander Ustinov’s possible opponent on Saturday’s huge Stuttgart boxing card. Batchelder suffered a nasty cut and was forced to withdraw from the collision. Replacing him is Brazilian national champion Rafael Zumbano (20-4-1, 17 KOs), who will meet WBA-ranked Ustinov (14-0, 12 KOs) in a non-title eight-rounder. The main event of the show is the WBC heavyweight showdown between champion Vitaly Klitschko and mandatory challenger Juan Carlos Gomez.
