Vinc Pichel struck quickly in the sudden-death round on The Ultimate Fighter on Friday night.
The 29-year-old was able to secure an arm-triangle 44 seconds into the round against John Cofer, allowing the Team Cruz fighter to move on to the quarterfinals.
"When your game plan fails, you go for broke and that's what I did," said Pichel after the fight.
"It's a tough pill to swallow when you lose... It's just kind of upsetting," said Cofer.
