UFC 153 is almost here.
Also featured on the card are welterweights Erick Silva and Jon Fitch, Glover Teixeira, and the return of Antonio Rodrigo Nogueira.
Here are a few extra tidbits that you may or may not know about tomorrow's fight card.
Although many consider Brazil the birthplace of MMA, UFC 153 will only be the fifth UFC event in the country.
UFC Brazil, which featured a young Vitor Belfort knocking out Wanderlei Silva in 44 seconds, took place in 1998.
Nearly 14 years later, the UFC returned for UFC 134. Like tomorrow's main event, Anderson Silva was featured in the main event.
Anderson Silva and Stephan Bonnar weren't originally what the UFC had planned for the main event.
A featherweight title fight was in the works with Eric Koch taking on champion Jose Aldo.
When Koch got injured, Edgar stepped in as he was preparing to move down from 155 lbs.
This too got scrapped when Aldo got injured.
The injury bug also hit Quinton "Rampage" Jackson who was set to take on Glover Teixeira.
Although we will not get to see "Scarface," "Rampage" and "The Answer," we will get to see a Spider take on an American Psycho.
For the first time since UFC 137 the main event of a UFC number card will only be three rounds.
Last year the UFC made the decision to make all main events five rounds regardless of whether or not it's a title fight.
Thanks to the fight being put together on such short notice, though, the main event will only go three rounds.
Many people believe three rounds won't be needed as they expect Anderson Silva to KO Bonnar.
If you watched the weigh in's earlier today, you may or may not have got the joke when Phil Davis and Wagner Prado starred down each other.
The two met at UFC on Fox back in August.
Sadly for the two, their fight ended in a no contest when Davis accidentally poked Wagner in the eye.
Wagner was extremely distraught as the doctor did not let him continue.
Hopefully there will be a clear winner this time around.
Up-and-coming welterweight Erick Silva has looked impressive thus far in his UFC career.
After debuting at UFC 134, he lost a controversial fight to Carlo Prater at UFC 142.
Silva was disqualified for strikes to the back of the head after it appeared that he won the fight.
Both events took place in Rio de Janeiro, Brazil, where tomorrow's fight will take place.
UFC 153 will feature eight fighters who fought on The Ultimate Fighter.
Diego Brandao and Rony Jason won their season's of the show with Jason winning TUF Brazil.
The most famous from the show on the card is of course Stephan Bonnar who along with season 1 winner Forrest Griffin had one of the greatest fights in UFC history.
Antonio Nogueira coached on Season 8 of the show, and Anderson Silva gave Griffin one of the worst beat downs of his career.
When you look at what Anderson Silva has accomplished since he came to the UFC in 2006, it's hard to remember that he had an MMA career before it.
Silva had a respectable 17-4 record before he came to the UFC.
One of the losses of course was the DQ against Yushin Okami.
One was by decision and the other two came by way of submission.
Stephan Bonnar on the other hand has never been submitted and his TKOs were thanks to cuts.
Although it may mean nothing for tomorrow's main event, it may be hard to believe that Bonnar has something on his record that looks better than Silva's.
With 19 knockouts, Anderson Silva leads the card with the most (T)KO's.
That includes his light heavyweight knockouts over Forrest Griffin and James Irvin.
Dave "Pee Wee" Herman is behind Silva with 15 KO victories.
Fabio Maldonado and Glover Teixeira are right behind with 12 and 11 KO's.
When it comes to submissions, Antonio Nogueira comes second to none.
He leads the way with 20 submission victories.
Lightweight vet Gleison Tibau is second on the card with 11 wins by submission.
Let's face it.
Stephan Bonnar a ton of heart and participated in the fight that may have saved the UFC, if not all of MMA.
But Bonnar has not had the greatest career as far as who he has defeated.
While he holds wins over Brian Ebersole and Keith Jardine, he has lost to Forrest Griffin (X2), Lyoto Machida, Rashad Evans and Jon Jones.
This alone is one of the main reasons why fans are wondering how he got this fight against Anderson Silva.
Bonnar is riding a three-fight winning streak and has never been submitted or knocked out.
But it's hard to believe that he will walk in and take out the greatest fighter in the world. Even with a size advantage, Silva should be a lot quicker and more precise with his strikes.
