According to the Russian heavyweight's management, Sidelnikov was bothered by a broken nose during his training for his Jan. 24 fight against Paul Buentello.
"Not wanting to miss any training time leading up to 'Day of Reckoning,'" M-1 Global says. "Kirill followed the advice of a coach not affiliated with M-1 who gave him a nose spray commonly used in Russia to help treat some of his symptoms. It is M-1's belief that the nose spray is what contained the Stanozol.
"For those that are skeptical of this explanation, we believe Kirill's account is true based in large part to his physique. If he had been using large amounts of Stanozol on a regular basis, we believe that the frame of his upper body would have contained leaner muscle that had more definition."
M-1 Global will not appeal the suspension and fine handed down by the California State Athletic Commission. Sidelnikov was fined $2,500 and will be suspended until Jan. 18, 2010.
"Even though it was only a common nose spray that he used to treat an injury, an athlete must take full responsibility for what he puts into his system at all times," M-1 Global says.
Sidelnikov lost to Buentello via stoppage due to strikes in the third round.
