"The Ultimate Fighter: Brazil 4" will have a new main event. According to a report from Adriano Albuquerque and Rafael Marinho at Combate, and later confirmed by MMAFighting, the show's finale will now be headlined by a five-round middleweight bout between Lyoto Machida and Yoel Romero.

"The Ultimate Fighter: Brazil 4's" finale has been marked by some curious changes. The event was initially slated for June 27 in Sao Paulo, Brazil, but was then later moved to Miami, Florida. It was originally set to be headlined by welterweights Rick Story and Erick Silva. That fight has been downgraded to co-main event status.

But whatever the UFC's reasons are, this is a crucial fight for the former UFC Light Heavyweight champion. He's coming off a submission loss against Luke Rockhold just this past April, and will need a win to re-establish himself in the division. Machida is 3-2 since moving to the middleweight division. He took UFC Middleweight Chris Weidman to the full five rounds back in July last year when he lost a unanimous decision. "The Dragon" followed up that loss with a TKO of the always-game C.B. Dolloway.

He faces an Olympic wrestling Silver medalist in Romero, who is undefeated in his five fights in the UFC. He will finally get inside the Octagon after his two bouts with Ronaldo "Jacare" Souza were cancelled twice. Romero is coming off a controversial third-round knockout victory against Tim Kennedy back in September. During his undefeated five-fight run in the UFC, Romero has won four of his five fights via stoppages, and is 9-1 in his professional mixed martial arts career.

"The Ultimate Fighter: Brazil 4's" finale will also be featuring the season's finalists in the lightweight and bantamweight divisions, a welterweight fight between Lorenz Larkin and Santiago Ponzinibbio, along with a heavyweight tiff between Nikita Krylov, and Marcos Rogerio de Lima.
