CHENGDU, China — Ray Austin of the United States earned a victory over Andrew Golota on Friday when the Polish fighter declined to come out for the second round of their non-title WBC heavyweight bout.

Austin knocked down Golota only 10 seconds into the bout between former title contenders promoted by Don King. Golota hit the deck a second time in the round, but referee Mike Griffin ruled it a slip.

Golota complained of an injury to his left biceps apparently from the first round, officials said.

"It feels great to redeem myself," said Austin, who lost a heavyweight title fight last year to Vladimir Klitschko. "I didn't get to show all that I wanted, but I'm happy I won."

There were three other fights on the card.

In a WBC strawweight title fight, Juan Palacios of Nicaragua won a seventh-round TKO over Teruo Misawa of Japan when the referee stopped the fight 2:28 in the round.

Marco Antonio Barrera of Mexico Sammy Ventura of Mexico on a fourth-round TKO of their lightweight fight and Devon Alexander of the United States improved to 16-0 with a fourth-round TKO over Lee Sun-haeng of South Korea.

Alexander is the WBC's No. 1 title contender at super lightweight and is in line for a title fight with Timothy Bradley.

The fight card in Chengdu coincided with a World Boxing Council convention being held in the city.
