You only get one Ultimate Fighting Championship (UFC) debut!
Only one fighter outside The Ultimate Fighter (TUF) finals made his first Octagon appearance at UFC Vegas 121 last night (Sat., Sept. 26, 2026) inside Meta Apex in Las Vegas, Nevada—and “The Stache” made quite the impression.
With the dust now settled, let’s hand out a grade to UFC Vegas 121’s lone rookie.
One caveat: I do not grade fighters competing in TUF finale bouts. I’ll evaluate them after their first post-TUF Octagon appearance. That said, shoutout to Tina Black—she is awesome and violent.
Luis Hernandez
It did not last long.
“The Stache” immediately charged forward with a combination, but Dumas moved out of danger. Hernandez then cracked him with an overhand left, clinched him against the fence and dragged him to the canvas.
When Dumas worked his way back to his feet, Hernandez wrapped up a standing guillotine. Dumas quickly tapped, ending the fight just 57 seconds into the opening round (watch highlights).
While Dumas is not particularly good, this was still a breakout performance for Hernandez, who immediately came across like a potential fan favorite. His wild celebration and over-the-top personality certainly helped, as did the matchmaking joke that practically wrote itself: an active sheriff’s deputy fighting a convicted felon.
You cannot make this stuff up.
Hernandez now owns a perfect 9-0 record with a 100 percent finish rate, including six submissions and three knockouts. Seven of those victories have come in the first round.
He is not the most polished or technically refined fighter, but he is an absolute berserker who immediately forces opponents into chaos. That aggression will give plenty of fighters problems, although I still want to see what happens when someone survives his initial storm and forces him to fight deep into the second or third round.
Hernandez intends to drop to Welterweight for his next appearance. If that happens, I would match him against Nikolay Veretennikov.
If he remains at Middleweight, give him Ryan Loder.
Final grade: A+
