UFC heavyweight Chase Sherman has been suspended by USADA for nine months after testing positive for anastrozole.
USADA confirmed Sherman’s test failure on Tuesday. Anastrozole is an anti-estrogen drug that is used to treat breast cancer, but in sports it’s commonly used to counteract estrogen produced from consuming substances that boost testosterone.
Sherman’s test failure comes from a test issued in May when he defeated Ike Villanueva via second-round TKO. The heavyweight will be eligible to compete again after Feb. 13, 2021.
“Upon being added to the UFC Anti-Doping Program, an athlete who voluntarily and promptly discloses the use of a prohibited substance prior to testing will not be deemed to have committed a violation if they test positive from the prior use,” USADA’s official statement read.
