UFC’s statement reads:
The UFC organization was notified today that the U.S. Anti-Doping Agency (USADA) has informed Brock Lesnar that his in-competition sample collection from July 9, 2016, at UFC 200, has tested positive for the same substance as his previously announced out-of-competition collection on June 28, 2016.
USADA, the independent administrator of the UFC Anti-Doping Policy, will handle the results management and appropriate adjudication of this case. It is important to note that, under the UFC Anti-Doping Policy, there is a full fair legal review process that is afforded to all athletes before any sanctions are imposed. The Nevada State Athletic Commission also retains jurisdiction over this matter as the sample collection was performed at UFC 200 in Las Vegas.
Consistent with all previous potential anti-doping violations, additional information will be provided at the appropriate time as the process moves forward.
As the most recent failed test is flagged for the same substance as the previous one, the two tests will probably be amalgamated together to count as one single anti-doping violation, but it could and probably will lead to further sanctioning.
As of writing, there has been no official statement from the Brock Lesnar camp, or from WWE.
We will have more information as soon as it is available.
