UFC star T.J. Dillashaw says he's been informed of an "adverse drug test" following his January fight with Henry Cejudo ... and he will be giving up his UFC bantamweight title so he can "deal with this matter."
Dillashaw isn't specific about what P.E.D. he tested positive for following his Jan. 26 loss -- but says he's "disappointed" and trying to figure out what happened.
"To all my fans, I wanted to be the first one to let you know that USADA and the NYSAC have informed me an adverse finding in a test taken for my last fight," Dillasahw says.
