A purse of more than $10,000 is being put forth for the main event of Saturday's Rumble in Richmond, an 11-fight card featuring mixed martial arts, Muay Thai kickboxing and boxing.

For promoters, though, it'll be money well spent if it results in some repeat business.

"We want the people of Richmond, who haven't had something like this in a long time, to want to come back to the next event," said Paco Damian, part of Paco & LTD Productions. "We have two fighters with very close records, and everyone should be entertained by a good fight."

The card, which begins at 6 p.m. at the renovated Richmond Memorial Auditorium, features four MMA bouts sanctioned by the International Sport Combat Federation.

San Francisco's Chris Cariaso (8-1) and Oakdale's Rolando Velasco (7-1) will be fighting for the vacant ISCF MMA world bantamweight title in the main event.

According to Damian, Cariaso tries to apply constant pressure to his opponents, with Velasco's strength coming as a striker.

There are also six title fights sanctioned by the International Kickboxing Federation, including a world middleweight bout between Daniel Kim (10-3) and Dion Paminato (12-4).

A light welterweight boxing match between Al Simpson and Victor Cortez, both making their pro debuts, is also being held.

The weigh-ins are today at 5 p.m. at the auditorium, which used to host boxing matches until the mid-1990s.
