Junior dos Santos is set to give Tai Tuivasa the biggest test of his career.
On Thursday, officials announced that dos Santos and Tuivasa will meet in the heavyweight headliner of UFC Adelaide on Dec. 2. The bout was first reported by Combate.
This will be dos Santos’s second fight since returning from temporary suspension tied to a potential USADA violation of which he was cleared in April. The former heavyweight champion would go on to fight Blagoy Ivanov at UFC Boise, winning a five-round unanimous decision to improve his pro record to 19-5. Dos Santos, 34, has alternated wins and losses in his last nine contests.
Tuivasa (8-0) has seen his hand raised in all three of his UFC appearances. A native of Sydney, the 25-year-old Tuivasa owns first-round knockouts wins over Cyril Asker and Rashad Coulter inside the Octagon, and most recently defeated another former heavyweight champion, Andrei Arlovski, by unanimous decision at UFC 225 in June.
UFC Fight Night 142 takes place at the Adelaide Entertainment Centre in Adelaide, Australia, on Dec. 2.
