The Octagon returned to Brazil Saturday night for UFC Fight Night 62 with plenty of interesting finishes and bouts despite a lack of ranked fighters.

In the main event, Demian Maia dealt Ryan LaFlare his first pro defeat with a decision victory. The former No. 1 contender to the UFC middleweight belt, Maia kept himself on the cusp of title contention at welterweight by winning his second straight.

Erick Silva sent Josh Koscheck to his fifth straight loss, locking up a guillotine choke in the first round. Silva scored his 11th opening round finish with the victory, dominating Koscheck throughout the action to improve to 3-1 in his last four overall.

Leonardo Santos and Amanda Nunes each impressed in front of the Brazilian crowd, as Santos topped Tony Martin with a second round rear-naked choke and Nunes stopped Shayna Baszler in under two minutes with strikes.

Gilbert Burns, who was scheduled to meet Josh Thomson in the co-main event, overcame a slow start to submit Alex Oliveira in the third round. After having his eye almost completely swollen shut, Burns locked up an armbar after a triangle choke attempt failed to remain unbeaten.

Godofredo Pepey kicked off the main card with a quick submission of Andre Fili, earning his third straight victory in the first round.

Four of the early prelims ended quickly, as Kevin Souza and Ferdy Serrano each scored knockouts, while Leandro Silva and Christos Giagos picked up submission victories. Souza’s triumph came in just 91 seconds over Katsunori Kikuno.

Francisco Trinaldo and Leonardo Mafra each added decision wins.

The Silva victory had plenty of controversy around it, as Drew Dober claimed he didn’t tapped out and there didn’t appear to be a signal from him while the guillotine was locked in.

Burns, Pepey, Souza and Serrano each picked up “Performance of the Night” bonuses and $50,000. The attendance was announced at 7,707.
