UFC heavyweight Chase Sherman has been suspended for nine months for an anti-doping violation related to an in-competition sample collected on May 13, USADA announced Tuesday.
Sherman tested positive for anastrozole during a drug test at UFC Fight Night 171. Anastrozole is in the class of hormone and metabolic modulators and is banned at all times, according to the UFC Anti-Doping Policy.
Sherman provided evidence that he used the banned substance prior to entering the UFC Anti-Doping program, but he still faces a violation because he did not declare anastrozole on his onboarding declaration form.
