The planned rematch between Lyoto Machida and Dan Henderson, originally scheduled for UFC on FOX 19, has been cancelled.
According to an official UFC announcement, Machida has turned himself in after using a banned substance in an out-of-competition drug test last week. Machida has stated that he was not aware at the time that the as-of-yet unidentified substance was banned both in and out of competition.
Through a press release, the UFC commented on the situation:
"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."
As of now, there is no announced plan in place for filling the main event for UFC on FOX 19, although regardless, Dan Henderson will likely not participate. The UFC is reportedly finding him a new fight that will take place at a later date.
Unsurprisingly, he does not seem very happy about this new situation:
Machida will likely face some form of a suspension following this incident, although the fact that he turned himself in may mitigate the severity of the punishment.
