TJ Dillashaw is no longer the UFC world bantamweight champion.
Dillashaw (16-4) announced Wednesday morning that he "voluntarily abandoned" the 135-pound UFC title after being informed by the New York State Athletic Commission, the United Anti-Doping Agency States of a "negative finding in a test that was done for my last fight". ESPN confirmed the validity of the statement from several sources.
Dillashaw contained no further information. NYSAC and USADA officials were not immediately available for comment.
Dillashaw, 33, will be suspended by the NYSAC for a year until January 19, the date of his last fight, according to ESPN. It is currently unclear whether USADA will suspend it for longer. A formal announcement is expected on Wednesday morning.
Dillashaw dropped back to flying weight in January to claim Henry Cejudo for the belt, but lost the battle over TKO in just 32 seconds.
He originally won the bantamweight title at UFC 173 in May 2014, when he unleashed one of the biggest surprises in the history of the UFC by beating former champion Renan Barao. While losing the belt in January 2016, Dillashaw won the title for the second time in November 2017 when he knocked on Cody Garbrandt's UFC 217. He defended the belt successfully in August when he defeated Garbrandt again. Then he set the goal flyweight.
