UFC 142 marks the promotion's next effort to bring the sport back to the HSBC Arena in Rio de Janeiro, Brazil.
The event will be headlined by a featherweight tilt between champion Jose Aldo takes and Chad Mendes, while middleweight sluggers Vitor Belfort and Anthony Johnson will battle in the co-main event of the evening.
While the headliner and supporting act remain intact, their have been several bouts that have fallen through thanks to injury, and new opponents have since been targeted for these respective matches.
UFC newcomer Siyar Bahadurzada of Golden Glory was originally scheduled to take on Brazilian prospect Erik Silva; however, the Afghan native was bitten with the injury bug and was forced to pull out of the welterweight affair.
In his place will be Carlo Prater, a veteran of the WEC who owns impressive victories over UFC veterans Spencer Fisher, Melvin Guillard and Carlos Condit.
Wolfslair product Rob Broughton was likely on his last leg with the UFC when he earned a bout with Brazilian Ednaldo Oliveira.
"The Bear" was subsequently injured in the lead in to his heavyweight tilt; however, what is one man's loss is another man's gain, as former UFC contender Gabriel Gonzaga earned his way back to the Octagon.
After exiting the promotion on the heels of a two-fight skid, Gonzaga earned a submission victory over Parker Porter, which earned him the Reality Fighting heavyweight championship in the process.
Former contender Paulo Thiago was scheduled to take on veteran Mike Pyle, that is before the former special forces military officer was also a victim of injury leading into the bout.
In his place will be fellow countryman Ricardo Funch, a veteran of the Octagon who will be joining his teammate, Gabriel Gonzaga, in his return to the UFC.
Funch went 0-2 against notable opposition in Johny Hendricks and Claude Patrick, though, he picked up a decision victory over Ryan Quinn this December, which helped ease the pain of his two career defeats.
Injury was not the case here, as Stanislav Nedkov was well prepared for his light heavyweight encounter with Fabio Maldonado, though, visa issues have detained the powerhouse wrestler from exiting his native Bulgaria for the time being.
Now, Maldonado will take on fellow countryman Caio Magalhaes, an undefeated prospect who will be moving up to the 205-pound tilt following a successful run as a middleweight.
