Cheick Kongo has been matched with Antonio Rodrigo Nogueira for UFC 149.
It will be the Brazilian’s first fight since his December loss to Frank Mir, which resulted in a broken upper arm-bone thanks to a completed kimura.
The fight, which takes place July 21, was announced by UFC president Dana White early on Wednesday.
Kongo goes into it off the back of a loss to Mark Hunt at UFC 144 in February. The first-round TKO stoppage snapped a two-fight win streak for the heavyweight gatekeeper.
Nogueira is 2-2 in his last four with the loss to Mir preceded by a stoppage win over Brendan Schaub at UFC 134 in Brazil.
That clash with Schaub was another comeback fight for Nogueira, who had been out of action over a year after undergoing double hip surgery and a knee operation.
Often thought by fans to be much older than his 35 years, Nogueira has accumulated significant wear and tear during years of often gruelling professional competition.
Likewise Kongo, 36 years old, struggled with a crippling back condition for some time. It was particularly bad around the time of his UFC 99 fight with Cain Velasquez - Kongo had such severe sciatica he was unable to kick or pull guard properly.
Both men now claim to be healthier than they have been for a long time, but the proof will come in January. While the match is a classic striker versus grappler pairing, it also puts two veterans against each other and probably hastens the losers path into retirement.
