The inaugural Sengoku Raiden Championship fight card of 2010 is starting to take shape with the addition of Wilson Reis (9-1), Yuji Hoshino (16-7-7), and Shigeki Osawa (4-1).

SRC 12, which is scheduled for March 7 at Ryogoku Kokugikan in Tokyo, will air on HDNet in North America. The fight card is punctuated by the SRC middleweight title bout-cum-rematch between Jorge Santiago and Mamed Khalidov.

Wilson Reis, former EliteXC 140 lbs. champion, makes his SRC and Japanese debut against Yuji Hoshino.

Reis, a highly touted grappler who holds a black belt in Brazilian Jiu Jitsu under Roberto Godoi, was a favorite to win the featherweight tournament during the first season of Bellator Fighting Championship. After defeating Henry Martinez via unanimous decision in the first round of the tournament, he was upset by the eventual winner, Joe Soto in the semi-final round.

He has since restored his winning way with consecutive victories over Roberto Vargas and Dwayne Shelton at Bellator 10 and Locked in the Cage 1, respectively.

Hoshino, a former Cage Force featherweight champion, made his Sengoku debut last November at Sengoku 11 opposite Marlon Sandro. Having suffered a first-round KO loss in the bout, he looks to rebound with an emphatic victory over the very game Reis. He holds notable victories over Shooto veteran, Antonio Carvalho and former Sengoku lightweight champion, Satoru Kitaoka.

Former collegiate wrestling dynamo, Shigeki Osawa returns for his second appearance in the main card of SRC against a Korean grappler, Kyung Ho Kang (4-2). Osawa had garnered a mountain of accolades during his amateur wrestling career; hailed as a "gem that appears once every 20 years," he capped off his illustrious wrestling career with a gold medal at the World Collegiate Wrestling Tournament in Greece.

In his last fight at Sengoku 11, he incurred the first loss of his career against the British prospect, Ronnie Mann.

Kang became a Korean version of TUF winner when he emerged victorious during the third season of "Go! Super Korean," a reality TV show series similar in format and premise to The Ultimate Fighter. He has competed in Spirit MC, Chinese-based Art of War, and DEEP.
