Phillip Jack "CM Punk" Brooks teases his fans on Twitter about a possible in-ring comeback.

CM Punk trolls his fans on Feb. 20 in a tweet that said, "Recently, a lot of people have been asking me if I'm 'in'... 1/2." He then made another tweet where he posted a promotional photo of the upcoming "All In" event and he said, "You know I'm in. #EverbodyIn #cubs @cubs 2/2."

CM Punk's tweets were made following the news that independent wrestling stars Cody Rhodes and The Young Bucks (Matthew and Nicholas Massie) were planning to host a professional wrestling event named "All In" with the goal of filling a venue that fits 10,000 people. According to GiveMeSport, the event is rumored to take place in Chicago (CM Punk's hometown), London, San Francisco and Ontario, California. GiveMeSport also said that there is a possibility for the two stars to partner up with Ring of Honor (ROH), although there is still no news about a potential deal.

Moreover, GiveMeSport also noted that since the announcement of the said event, there has been a rumor circulating that The Young Bucks have been trying to recruit CM Punk for the show either for an in-ring return or an appearance. In an interview with Rolling Stone on Nov.r 14, Nicholas said that they would love to work with CM Punk in the Bullet Club. When asked if they had reached out to CM Punk about their desire, Matthew said that he talked to CM Punk a lot, bugging him for a year or two. He said that at one point he realized how aggressive he was being and that he had to let CM Punk make his own decision. Furthermore, he said that CM Punk told him he will be the first person CM Punk will call should he decide to go back to the wrestling business.

Whether or not CM Punk makes a comeback will be officially confirmed in the "All In" event happening in September.
