Thursday morning, UFC middleweight champion Luke Rockhold was randomly drug tested by the U.S. Anti-Doping Agency ahead of his UFC 199 rematch with former middleweight champion Chris Weidman.

Rockhold posted about the random test on Instagram.

Blood and urine for breakfast anyone? Surprise visit from USADA this am. Happy to participate in the movement to a clean sport.
