Tom Aspinall currently sits as the undisputed heavyweight champion after Jon Jones vacated the belt. Aspinall is scheduled to defend his title against Ciryl Gane in the main event of UFC 321 on Oct. 25. Cortes-Acosta believes he'll likely face the Englishman should he beat Pavlovich.

‘Mountain Tiger’ Zhang Mingyang introduced himself to the American fans in April when he left former title challenger Anthony Smith in a pool of his own blood for his retirement fight. This was Mingyang’s U.S. debut and 19th career finish.
