Former Olympian Harrison loses again

Audley Harrison's dream of becoming a world heavyweight champion was all but finished when he lost in three rounds to unheralded Michael Sprott on Saturday.

The 2000 Olympic superheavyweight champion, whose career appeared to have been revived by a knockout victory over Danny Williams, was floored by a right hand at the end of the third round.

Referee Ian John-Lewis removed Harrison's mouthpiece, immediately summoning medical help, and it was several minutes before Harrison was assisted to his feet and helped back to his corner on wobbly legs.

On the same card, Amir Khan needed only 55 seconds to beat Mohammed Medadji for his 11th victory as a pro in a scheduled eight-round contest as a lightweight.

The Olympic silver medalist at the 2004 Athens Olympics is British boxing's biggest rising star and promoter Frank Warren hopes to line him up with a world title shot later this year.

Another British lightweight, Graham Earl, lost his WBO interim title to Australia's Michael Katsidis in an eventful and thrilling fight that only went five rounds.

Katsidis had Earl in so much trouble that the British fighter's corner threw in the towel, which these days doesn't count as a stoppage. Earl hit back to floor the Australian but his corner called off the fight at the end of the fifth with the Englishman taking too much punishment and with a cut opening above his left eye.
