Kirill Yurievich Sidelnikov (Russian: Кирилл Юрьевич Сидельников) born August 17, 1988, is a Russian professional mixed martial artist and grappler, fighting out of Stary Oskol, the same hometown as Fedor Emelianenko with whom he is a training partner. He fights for M-1 Mixfight.Sildelnikov fought for the first time on North Americain soil at Affliction: Day of Reckoning, losing to Paul Buentello. Following the fight Kirill Sidelnikov was suspended for testing positive for Stanozolol. The suspension period is retroactive to the conclusion of the bout on January 24 and runs through January 18, 2010. He has been fined $2,500. The mere presence of Stanozolol in the system constitutes a violation under the new testing procedures for CSAC. Sidelnikov claimed that the substance had been prescribed to him to recover from injury, and hence he maintains that he was unaware of his use of the banned substance. He is among the youngest fighters to compete in a major pay per view event in combat sport history. However, due to his recent suspension from competition in the United States he has solely chose to compete within the M-1 organization, the same organization that gave him his first fight. Wikipedia
