Brave Sakio Bika battles hard but loses on points

SYDNEY'S Sakio Bika has lost his WBC world super middleweight belt to unbeaten American Anthony Dirrell in an ugly clash at the StubHub Centre in California.

But unlike a string of Aussie boxers recently knocked out in their shots at world titles, the Cameroon-born Bika went the full 12 rounds before losing a unanimous points decision.

The pair was involved in a heated and controversial draw last December in Bika's first title defence, with the Australian claiming Dirrell caught him with a low blow.

The rematch wasn't pretty either, with both fighters guilty of leading with their heads and wrestling in clinches.

The judges scored the fight 117-110, 116-111, and 114-113.

Bika is the fifth Australian fighter in four months to be beaten on the world stage after Alex Leapai, Daniel Geale, Blake Caparello and Jarrod Fletcher all hit the canvas.

The 29 year-old Dirrell is the second fighter in two weeks to have beaten cancer and won a world title at the expense of an Aussie. He was diagnosed with non-Hodgkin's lymphoma in 2007, and underwent chemotherapy.

Last weekend, fellow American Daniel Jacobs dominated Fletcher after overcoming osteosarcoma in 2011.
