Last week, WBA super middleweight champion Mikkel Kessler speculated that Anthony Mundine was looking for way out of their planned fight when Mundine talked of returning to pro rugby.  Now, according to the Associated Press, Kessler is the one pulling out of the bout, due to an injured back.  The Associated Press attributed the story to Mundine's manager, Khoder Nasser. The bout between Kessler (rated #2 by Boxingtalk) and Mundine (Boxingtalk #7) was scheduled for May 11, 2005 at the Sydney Entertainment Center.
