Oddly enough, Punk was responding to a troll on Twitter when the news broke.
Former WWE Superstar and current UFC fighter CM Punk last fought in an MMA match back in September 2016 where he lost in under two minutes against Mickey Gall. His cross-over to mixed-martial-arts helped the UFC build a bigger fan base. But Chicago is an important location for Punk - it's his hometown, so this fight will carry even more significance than it already does.
All signs seem to point towards a matchup with Mike "The Truth" Jackson, who was originally vying for a shot at Punk in his UFC debut back in 2016.
