In anticipation of CM Punk's long-awaited UFC debut, the promotion released the trailer for an upcoming documentary detailing his journey from the squared circle to the Octagon.
Since signing with the UFC in December 2014, the former WWE star has had difficulty finding a suitable opponent, faced accusations that his career change is a publicity stunt, and dealt with a series of injuries.
Punk is scheduled to fight Mickey Gall at UFC 203 on Sept. 10 in Cleveland.
