If there is one thing we have learned from the UFC it is to expect the unexpected when you are expecting absolute the worse.

The promotion heads to Sao Paulo, Brazil Saturday night for a card that has undergone some serious makeovers in recent months and weeks since being announced.

UFC Fight Night 137 was to feature Glover Teixeira and Jimi Manuwa in a key light heavyweight contest. Neither Teixeira or Manuwa are still attached to the card, as Thiago Santos and Eryk Anders are now in the main event.

Santos and Anders are not quite at the same level in terms of marquee names as Teixeira or Manuwa, but both men will deliver. Santos, a native of Rio de Janeiro, owns 13 finishes among his 18 career wins, including a February TKO of the red-hot Anthony Smith.

Anders, a former University of Alabama football player, started out his career 10-0 with a pair of Octagon wins before suffering a split decision loss that same month as Santos’ win to Lyoto Machida. He rebounded in August, though, landing a head-kick finish on Tim Williams in the third round.

Both of these men know what it takes to make a statement, and having the opportunity to headline a card on FOX Sports 1 is a perfect time to deliver another.

We also get to see Alex Oliveria back in action, as he meets Carlo Pedersoli Jr., along with Antonio Rogerio Nogueira meeting Sam Alvey. Former champion Renan Barao, who badly missed weight as you can see below, faces Andre Ewell and Randa Markos kicks off the main card vs. Marina Rodriguez.

And for as interesting as the main card is, the UFC Fight Pass prelims might be the “can’t miss portion” of the night. Hector Lombard faces Thales Leites in a battle of two veterans in desperate need of a victory, while former Invicta FC champion Livia Renata Souza and Alex Chambers are on my short list for “Fight of the Night.”
