Arthur Abraham (38-4, 28KOs) and WBO super middleweight champion Robert Stieglitz (46-3, 26KOs) held open workouts ahead of their trilogy showdown, taking place this Saturday night at the GETEC Arena in Magdeburg, Germany. Abraham won a twelve round unanimous decision over Stieglitz in August of 2012, and the Stieglitz got revenge last March with a fourth rounds stoppage, after Abraham was unable to continue due to his eye getting swollen shut.
