Reigning UFC heavyweight champion Stipe Miocic currently does not have his next title defense scheduled, but it’s expected that he’ll take on the winner of UFC 207’s rematch between former champions Fabricio Werdum and Cain Velasquez.

Miocic and Dos Santos have squared off once before back at UFC on FOX 13 where “Cigano” got the nod after a five round slug fest. JDS most recently scored a dominant decision victory over No. 5-ranked Ben Rothwell.

Rothwell, however, doesn’t feel as if the Brazilian is deserving of a title shot, as he told Miocic to tell Dos Santos to ‘f*ck off’:

Who do you feel is most deserving of the next shot at Miocic’s heavyweight title?
