Two-time Olympic gold medalist Zou Shiming will reportedly get $500,000 and exposure from HBO when he takes on unheralded fighter Jesus Ortiga in the main event of Fist of Gold II on Saturday at the Venetian Casino & Resort Macao in Macau, China.

Zou, who will be fighting only his second boxing bout since turning pro earlier this year, will banner Saturday's HBO Pay-per-View card, which will also feature two world championship matches.

Coming off a unanimous decision victory over novice Mexican Eleazar Valenzuela, Zou enters the tournament hoping to continue his winning streak. The Chinese boxer will be facing an unknown fighter in Ortiga, who has a record of 3-1 with 2 KOs in four professional fights.

Supporting the six-round showdown between Zou and Ortiga are world title clashes between WBA and WBO flyweight champion Juan Francisco Estrada and Filipino challenger Milan Melindo, and IBF Featherweight king Evgeny Gradovich and Mauricio Munoz.

The card will also feature up-and-coming fighters like Dodie Boy Penalosa and Paul Fleming.
