According to Evgeni Kogan's twitter page, Fedor Emelianenko has chosen to observe the NSAC 90 day suspension issued following his loss to Big Foot Silva. As a consequence, he will not compete in Sambo this week-end.
From Kogan's twitter account:
"Fedor no longer competing in the Russian Combat Sambo champs over the weekend.
He is observing the 90 day suspension so that he can come back after that!"
