He fought seven more times, winning on each occasion, before travelling to the United Kingdom on 1 August 2003, where he defeated England's Matthew Barney for the Commonwealth super middleweight title.
His opponent, Britain's Carl Froch, who would go on to become the WBC World Super Middleweight champion, inflicted Adamu's second defeat in a row.
[3][4] The next fight of note for the now former Commonwealth champion took place on 18 June 2005 and meant that Adamu had to travel once more, this time to Canada.
His opponent in a challenge for the WBC inter continental title was Jamaican Otis Grant and the fight resulted in a third career defeat, again on points for Adamu.
In a fight that once more went the full 12 rounds, Adamu won a split decision over England's Carl Dilks to regain the title he first held in 2003.
