UFC Statement on Machida ...
The UFC organization was made aware today by the U.S. Anti-Doping Agency (USADA), the independent administrator of the UFC Anti-Doping Policy, that Lyoto Machida declared the usage of a banned substance during an out-of-competition sample collection last week. Machida stated that he was unaware that the substance was prohibited both in and out of competition and, in accordance with the UFC Anti-Doping Policy, his disclosure of usage will be taken into consideration by USADA during any potential results management and adjudication process.
Given this information, UFC officials have elected to remove Machida from his scheduled bout against Dan Henderson this Saturday in Tampa, Fla. Henderson will be re-booked for a new bout in the near future.
