2008-03-08 David Haye w rsc 2 Enzo Maccarinelli, O2 Arena, Greenwich, London, England - WBA/WBC/WBO/The Ring
Having decided to move up to the heavyweight division, Haye relinquished the WBC title on 12 May and a few days later he notified the WBA that he would be sending back his belt. Following that, Arslan was handed full WBA title honours on 16 June.
Although Haye relinquished the WBO title on 22 July, it took the body some while to fill his boots. Eventually, Victor Ramirez contested and won the vacant WBO ‘interim’ title when forcing Alexander Alexeev to retire after nine rounds at the Castle Guard Arena, Dusseldorf, Germany on 17 January 2009, being promoted to full championship status a few days after. Following that decision, Ola Afolabi knocked out Maccarinelli in the ninth round to win the vacant WBO ‘interim’ title at the MEN Arena, Manchester, England on 14 March. Originally, Maccarinelli was matched against Jonothon Banks but when he pulled out Afolabi stepped in at relavely short notice.
