Outside Australia, not many people know Green, or Mundine for that matter. He is perhaps most famous in the US for having a widely broadcast spar with James Toney when he was Interim Super Middleweight champion, and Toney a blown up heavy.

He somehow won the WBA Light heavyweight belt, then retired, abdicating the belt with out ever defending it. When he fought Mundine, he was massacred in 2006.
