Las Vegas - T.J. Dillashaw surrendered his UFC bantamweight crown on Wednesday after revealing a "adverse finding" in a doping test following a January loss in New York.
The 33-year-old American was stopped by flyweight champion Henry Cejudo in 32 seconds at Brooklyn, where Dillashaw submitted the sample found in violation, according to the US Anti-Doping Agency (USADA).
Dillashaw said in an Instagram statement.
The New York commission fined Dillashaw $10 000 and suspended him for one year for "violations relating to the use of a prohibited substance."
USADA followed with a statement confirming Dillashaw's positive test.
"In light of Mr. Dillashaw's social media post this morning, we can confirm that an in-competition test conducted by USADA on January 18, 2019 resulted in an adverse analytical finding," USADA said.
"In this instance, we are able to confirm the finding due to Mr. Dillashaw's public statement. The presumption of innocence under the rules is a vital part of an effective anti-doping program and it's only fair that Mr. Dillashaw be allowed due process before any conclusions are drawn."
