Briggs won the WBO title with a 12th-round knockout of Sergei Liakhovich in November 2006 but lost the title in his first defence against SultanIbragimov eight months later.
In February 2008, Wladimir beat Russia's SultanIbragimov to take the WBO crown - and his last fight was a seventh-round stoppage of former world champion Hasim Rahman in December.
