Dos Santos, who prides himself on being a clean athlete, has yet to respond to the accusations.
In the UFC’s prepared statement, they said,
“The UFC organization was notified today that the U.S. Anti-Doping Agency (USADA) has informed Junior Dos Santos of a potential Anti-Doping Policy violation stemming from an out-of-competition sample collected on August 10, 2017. Because of the proximity to Dos Santos upcoming scheduled bout at UFC 215 in Edmonton, Canada against Francis Ngannou, Dos Santos has been removed from the card and the UFC is currently seeking a replacement.
His upcoming opponent, Francis Ngannou was ready to notch a former champion to his resume of victories, and will no longer get that chance.
He took to twitter with a harsh reaction to today’s news.
