Wilcox, Ribeiro Official for Strikeforce 'Challengers 12'

Vitor “Shaolin” Ribeiro and Justin Wilcox both made weight today for their main event scrap at Strikeforce Challengers 12, going down Nov. 19 at the Jackson Convention Complex in Jackson, Miss.

A former Shooto and Cage Rage world champion, Ribeiro (155.6) was at one time arguably the sport's top lightweight. However, the jiu-jitsu black belt has dropped three of his last four fights, including his Strikeforce debut at “Heavy Artillery” in May. Ribeiro dropped a contentious split decision to Lyle Beerbohm. Prior to that, the Brazilian lost to world-ranked lightweights Shinya Aoki and Gesias “JZ” Cavalcante. Sitting between those two losses is a TKO victory over Katsuhiko Nagata at Dream 8.

Wilcox (155) is a former collegiate wrestler and professional bodybuilder who made his MMA debut in 2006. The American Kickboxing Academy product is 3-1 in Strikeforce competition and is riding a four-fight win streak heading into his bout with Ribeiro. Nicknamed “The Silverback,” Wilcox owns seven of his nine professional victories by decision.

Also featured on the card will be a light heavyweight scrap between Antwain Britt (206) and former University of Tennessee linebacker Ovince St. Preux (205.6), as well as a welterweight showdown between hard-hitting Marius Zaromskis (171) and durable Waachiim Spiritwolf (168.8).

Strikeforce Challengers 12 will air live on Showtime at 11 p.m. ET.
