Well, kind of.
Chad Mendes, who is coming off of two losses in a row, was flagged by USADA on June 10 for an undisclosed reason. He hadn't commented on the situation... until now.
Mendes tweeted this to his followers on Saturday.
USADA is not able to release further details until the adjudication process is over.
Mendes has previously been a top contender in the UFC featherweight division, only losing to Jose Aldo who was then champ. Now he's coming off two knockout losses in a row, most recently to Frankie Edgar and Conor McGregor. He has a 17-4 record.
