The former world champion of the WBA, heavyweight Nikolai Valuev (50-2, 34 KOs), has undergone another surgical procedure. This time the "Russian Giant" went to Germany for surgery to correct a problem with his nose. The 37-year-old boxer had multiple medical procedures in 2010 to correct injuries with his shoulder and hand. The operations have kept him away from the ring since November 2009, when he lost the title to David Haye.
