WBO super middleweight champion Robert Stieglitz (39-2, 23 KOs) has enlisted undefeated rising star Greg Proksa (23-0, 16 KOs) for sparring. Proska is traveling to Germany to help Steoeglitz prepare for his unification with WBA "regular" champion Dimitri Sartison (27-1, 17 KOs). Proksa's last ring outing was the preceding Saturday, where he knocked out Joe Rea in the fourth round.
