Trinaldo got the action started with a lightweight tilt against C.J. Keith. The fight streamed on Facebook, not on Fuel TV.
Trinaldo enjoyed great support from the hometown crowd in Brazil, as the event was held in Sao Paulo.
Trinaldo found himself in top position as the opening round drew to a close, and he easily won the first stanza, 10-9.
In the second frame, Trinaldo delivered a big slam before moving in for a submission attempt. He locked in an arm-triangle choke to earn the ref stoppage at the 1:50 mark of the second round.
For the second fight of the evening, Ildemar Alcantara took on Wagner Prado.
After a back-and-forth first round, Alcantara locked in a kneebar to earn a ref stoppage at the 2:39 mark of the second frame.
The 26-year-old Prado has now dropped back-to-back UFC fights, which clearly puts him on the chopping block as the promotion brings over fighters from Strikeforce.
The third fight of the evening saw Yuri Alcantara square off against Pedro Nobre, and it ended in controversial fashion.
Alcantara teed off on Nobre midway through the opening round, and ref Dan Miragliotta believed the punches were landing to the back of the head. The fight was waved off at the 2:11 mark of the opening round, as Alcantara's strikes were determined to be illegal.
The official ruling was a no-contest.
Later on the card, Edson Barboza def. Lucas Martins via submission at the 2:38 mark of round one.
With a victory, Bisping will receive a title shot against UFC champ Anderson Silva. Belfort is fighting for pride, as he will not get a title shot with a win over Bisping.
