Neil Magny had to have known he was basically walking into the lion's den.
Now he'll have to regroup following his first official loss in the UFC.
Magny (8-2, 1-1 UFC) was submitted Saturday by Sergio Moraes (8-2, 2-1 UFC) at the 3:13 mark of the first round at UFC 163 at HSBC Arena in Rio de Janeiro.
Heading into the pay-per-view card in Brazil, fighters from that country had built a staggering 36-9 record when fighting for the UFC against non-Brazilian opponents. Considering Magny's opponent is from Brazil and was the middleweight runner-up on the first season of "The Ultimate Fighter: Brazil," he had a tough task ahead of him.
Magny worked to use his nine-inch reach advantage early against Moraes. But after the two felt each other out with jabs and kicks, Moraes was able to get inside with Magny.
Once there, he dragged him to the canvas, and that's when he went to work with his Brazilian jiu-jitsu black belt skills.
Moraes immediately landed in side control on top on the canvas and quickly mounted Magny. He was able to transition to a triangle choke attempt and had Magny in plenty of danger. When he moved around and kept the choke, but mounted Magny again, the fight was as good as over.
Magny was forced to tap from the mounted triangle, a relatively rare finish that has happened just four times previously in the UFC.
"I feel like I'm just beginning, but I'm off to a good start," Moraes said after the fight. "Now I have to train more, evolve more and make my striking coaches happy, too. I am determined to learn, I'm always evolving on my feet and on the ground. And the best part of winning is being able to do this in front of this crowd, always cheering and pushing me on."
Magny, a former student of Miguel Torres who now trains in Colorado at the acclaimed Grudge Training Center, lost for the first time in the UFC after winning his official debut against Jon Manley in December. That win followed his appearance on Season 16 of "The Ultimate Fighter," where he was a semifinalist – although the fights in the house don't count toward his official record.
The loss was Magny's first in more than two years.
