The former WWE superstar made his return to the cage at UFC 225 in front of his hometown crowd at Chicago’s United Center.
Welcoming Punk back to the Octagon, which he hadn’t set foot inside since losing his professional debut at UFC 203, was his fellow mixed martial arts rookie Mike Jackson.
Punk failed to erase the memory of that humbling loss to Gall, who submitted him in two minutes and 18 seconds, suffering a unanimous decision loss to Jackson.
Unlike his bout with Gall, Punk started the fight light on his feet and was calm with his striking, landing a big right hand early on.
Although he showcased more confidence in his striking, Punk was very cumbersome and sloppy, leaving his guard down and eating counter punches.
Throughout the opening round, 39-year-old Punk tried to get the fight to the ground, where he felt like he had an advantage over Jackson.
And with a minute left on the clock, he managed to do so, albeit for a few moments before Jackson shook him off and got back to his feet.
Punk attempted to bring the fight back to the canvas early in the second but had his takedown attempt stuffed by Jackson, who was starting to loosen up with his punches and landing at will.
After being hurt with a right hand, Punk attempted to secure a guillotine choke but soon found himself on his back with ‘The Truth’ in closed guard and landing punches at will.
The opening stages of the third and final round of the much-maligned bout saw Punk yet again attempt to take Jackson down by tieing him up with a body lock.
That played right into Jackson’s hands as he continued to reverse him and land counter one-two combinations.
To his credit, Punk battled right until the end but was unable to mount any serious and sustained offence.
And his failure to do so led to him suffering his second consecutive defeat, one which will more than likely bring about the end of his time in the UFC.
UPDATE: Chicago native Punk was transported to hospital moments after his defeat to have a facial CT scan.
