Roy Jones, Jr.
On December 13, Rahman was matched with former WBA world champion John Ruiz, in a match for an Interim WBA heavyweight title (caused by Roy Jones, Jr. deciding whether he wanted to stay a heavyweight or return to Light Heavyweight). Rahman was favored, but he lost by (twelve round) unanimous decision and again was out of condition. Ruiz, who became interim titleholder with this victory, was upgraded to WBA heavyweight champion after Roy Jones Jr. vacated the title on February 20, 2004, choosing to fight Antonio Tarver for the WBC and IBO light heavyweight titles (already in 2003), rather than Ruiz.
