What was originally supposed to feature a featherweight title fight, the main event will now feature Anderson Silva returning to light heavyweight to take on Stephan Bonnar.
Also featured on the card is Antonio Rodrigo Nogueira taking on Dave Herman, Erick Silva vs. John Fitch and Glover Teixeira.
There are many exciting fights on the card. But here are the fighters that will take home Fight Night bonuses.
Submission of the Night: Antonio Nogueira
There are many great Brazilian jiu-jitsu fighters on Saturday's cards. In fact, a few are multi-degree black belts.
But there may not be any greater than "Big Nog."
With 20 submission victories on his resume, it's hard to go against him for Submission of the Night.
As great as Nog's submission game is, he has actually never won a Submission of the Night bonus.
The last time he fought in Rio, he got Knockout of the Night. Expect Nogueira to come out Saturday night and look for a submission any chance he gets.
Knock Out of the Night: Anderson Silva
There aren't many people giving Stephan Bonnar a chance Saturday.
I am one of those people.
Bonnar is as tough as they come. He has never lost by submission and does not have a true knockout on his record.
But he's taking on Anderson Silva, the greatest MMA fighter of our time and maybe the history of the sport.
Silva has 19 wins by KO. I'll take that over just about anybody's chin any day.
Fight of the Night: Teixeira vs. Maldonado
There are many great fights on this card.
But I believe the one that will steal the show is Glover Teixeira vs. Fabio Maldonado.
Between the two, they have 23 wins by KO and eight by submission.
Considering this is the only fight that features two Brazilians taking on each other, both men should be highly motivated to put on a good show for the hometown crowd.
