Roy Jones Jr. vs. Danny Green, billed as It's On, was a professional boxing match contested on December 6, 2009 for the IBO cruiserweight championship.

[1] 17 years after their first bout in 1993, Roy Jones Jr. and Bernard Hopkins, both of whom had become two of the most successful and decorated boxers in the sport since then, had finally come to an agreement for their long-awaited rematch.

As a precursor to their fight, both Jones and Hopkins had bouts scheduled on December 2, 2009, with both fighters needing victories in order for their rematch to continue forward.

Hopkins chose to face fringe-middleweight contender Enrique Ornelas,[2] while Jones proceeded with his planned IBO cruiserweight title match against Danny Green which had been agreed to since June.

"[7] However, less than a month later, Jones would launch a formal complaint, accusing Green of using illegal hand wraps and demanding his loss be overturned, though the decision was upheld.
