CM Punk has started competing in the UFC in late 2014, and he is closing to the year four of his UFC activity. However, CM Punk has competed only once in 2016, when Mickey Gall submitted him in the fight which lasted less than 3 minutes. Despite he is 39 years old, Punk doesn't even think of backing down from the challenge. The former WWE-champion should return to Octagon on June 9, in his hometown of Chicago, Illinois, and fight in the UFC 225 event. There are rumors that his opponent will be Mike Jackson, who also has a record of 0-1, with one loss to Mickey Gall. Punk's teammate at Roufusport, former UFC Lightweight Champion Anthony "Showtime" Pettis, believes that CM Punk has improved his abilities a lot since his UFC debut. (via MMAFighting.com) \u201cI see him every day, man. That guy\u2019s in the gym every day,\u201d Pettis said Monday on\u00a0The MMA Hour. \u201cHe\u2019s probably one of the hardest workers in the gym. He\u2019s always there, always improving, and yeah, he\u2019s definitely gotten better. You put that much time into , you\u2019re going to get better. He\u2019s working the gi, he\u2019s working no-gi. He\u2019s training with top-level UFC guys inside his weight class, so I think we should see a better performance.\u201d Anthony Pettis says CM Punk is present on a regular basis in the gym in Milwaukee. Even right after he was defeated from Mickey Gall, he hasn't lost his faith. Pettis claims that Punk is determined to improve. His 40th birthday comes soon and he hasn't fought since UFC 203 but, according to Anthony Pettis, this will not stop him. \u201cHe never stopped. Like, he didn\u2019t take a break,\u201d Pettis said. \u201cHe was right back at it. I think he had a couple injuries, but he was right back at it. \u201cIt doesn\u2019t surprise me. He\u2019s a competitor, man. And he loves the grind. I don\u2019t know what else he\u2019d be doing if he wasn\u2019t doing this. He\u2019s just, he\u2019s always in the gym. So in the short time I\u2019ve known him for his first fight to this fight, it\u2019s the same, the dude is just pushing hard, man. He\u2019s grinding, he\u2019s getting better, he\u2019s putting the mat time in, and there\u2019s no way around getting better besides putting the mat time in.\u201d What do you think, will CM Punk finally earn his first UFC victory in his hometown?
