All fighters but one made weight on Friday for Sengoku Raiden Championship 15, which takes place Saturday and airs live on HDNet. American Brian Cobb missed the weigh-ins entirely "due to poor health," but it appears that his lightweight battle with Kazunori Yokota will proceed as planned. Olympic judoka Hiroshi Izumi will face British veteran James Zikic in the evening's main event, while the undercard features the semifinals and quarterfinals for Sengoku's 2010 welterweight and bantamweight grands prix, respectively.
