UFC Welterweight George Sullivan Accepts 1-Year Suspension for Anti-Doping Violation

George Sullivan has accepted a one-year suspension from USADA “after declaring the use of a prohibited substance contained in a product that was inaccurately labeled,” the organization announced Tuesday.

Sullivan’s suspension is retroactive to Jan. 31, the day after his last Octagon appearance at UFC Fox 18.

The USADA statement is as follows:

Sullivan, 35, declared the use of Insulin-like Growth Factor-1 (IGF-1) on his sample collection paperwork when describing his use of a deer antler velvet product during an out-of-competition test conducted on July 13, 2016. IGF-1 is a prohibited substance in the class of Peptide Hormones, Growth Factors, Related Substances, and Mimetics, and prohibited at all times under the UFC Anti-Doping Policy, which has adopted the World Anti-Doping Agency (WADA) Prohibited List.
