While that fight will surely draw a ton of eyeballs, the main event is still technically Stipe Miocic — a hometown boy — defending his UFC heavyweight title for the first time against Alistair Overeem.
In what is being billed as a “co-main event,” Fabricio Werdum faces Ben Rothwell.
CM Punk officially signed with the UFC in December 2014, so this bout has been a long time coming. In the interim, he’s been training with Duke Roufus and the renowned Roufusport team in Milwaukee.
