UFC returns to Australia on Dec. 21, and heavyweight 
Mark Hunt will be on the main event of the Fight Night card.
 Sources close to the situation confirmed to MMAFighting.com  that Pride veteran Mark Hunt has verbally agreed to meet Brazilian  heavyweight 
Antonio "Bigfoot" Silva  in a five-round battle in Australia on Dec. 21, but the city or venue  for the event has not been determined. Combate first reported the news.
 At 39, Hunt returns to the Octagon after a third-round TKO loss to former UFC heavyweight champion Junior dos Santos at 
UFC 160 back in May. Prior to that loss, Hunt was riding a four-fight winning streak, including stoppages over 
Chris Tuchscherer, 
Cheick Kongo and 
Stefan Struve.
 Silva, a former EliteXC and Cage Rage heavyweight champion, looks to return to the win column following his first-round loss to 
Cain Velasquez  at UFC 160, when he had his chance to fight for the heavyweight  championship. Silva, who has lost twice to Velasquez in the UFC, is 2-2  under the Zuffa banner, having his arms raised after knockout wins over 
Travis Browne and 
Alistair Overeem.
