Shooto's South American branch is hosting one of its most important cards to date this Friday, with two world titles on the line and veteran referee Mario Yamasaki flying down to officiate.

Recent Strikeforce signee Siyar Bahadurzada (Golden Glory) will put his 183-pound belt on the line against Brazilian vet Carlos "Indio" Pereira (Dragon Fight Team), who hasn't lost a bout since 2007.

Fighting for Shinya Aoki's recently-vacated 167-pound strap will be South American title holder Luiz "Beicao" Ramos (Nova Uniao) and the Nogueira-trained Igor "Chatubinha" Fernandes, current #5 in the world Shooto rankings.
