This weekend, the UFC returns to Adelaide for just the second time in promotional history with a headlining fight that could determine the next contender for the UFC heavyweight championship.

In the main event, Tai Tuivasa (8-0 MMA, 3-0 UFC) looks to make it back-to-back victories over former UFC heavyweight champions when he takes on Junior dos Santos (19-5 MMA, 13-4 UFC).

Let’s take a look at the recent results of the two men in the main event:

Dos Santos scored a wide decision victory over Ben Rothwell in a five-round affair in April 2016 before being granted a shot at the UFC heavyweight championship for the third time in his career. Unfortunately for JDS, he lost to Stipe Miocic- the reigning UFC champion at the time- in an emphatic first-round TKO last May.

The Brazilian, who will be fighting twice in a calendar year for the first time since 2013, returned to action with a five-round unanimous decision win over Blagoy Ivanov in July.

Tuivasa has competed three times in the UFC thus far, scoring back-to-back first-round TKO/KO stoppages against Rashad Coulter and Cyril Asker before a unanimous decision win over Andrei Arlovski.

Until the Arlovski fight, Tuivasa had finished all of his professional MMA bouts by TKO/KO stoppage in the very first round and at just 25 years old he is the youngest ranked UFC heavyweight by some distance.

Dos Santos and Tuivasa share no common opponents throughout their professional MMA careers.
