Short-notice Hernandez chokes out Dumas in under a minute to open UFC Vegas 121 account

Luis Hernandez wasted no time announcing himself in the UFC, submitting Sedriques Dumas with a choke in under a minute at UFC Vegas 121 — his first octagon appearance after earning a contract on Dana White’s Contender Series less than two weeks earlier.

Hernandez had stepped in on just two days’ notice to replace Mickey Gall in the featured bout, a matchup that carried its own storyline: a Miami-Dade sheriff facing a fighter with a well-documented history of run-ins with the law. The crowd at the UFC APEX responded loudly from the opening bell.

The finish came quickly. Hernandez hurt Dumas badly with a punch early in the first round, then seized the moment to lock in the choke and force the tap. The submission moved him to 9-0 as a professional, with every single victory coming by way of finish.

After the stoppage, Hernandez delivered his signature celebration — a dance followed by a D-Generation X crotch chop — to a raucous APEX crowd that, by some accounts, was louder than it had been in some time.

For Dumas, the defeat extended a difficult run. He is now winless in his last five bouts and has not recorded a victory in over two years, leaving his UFC future in serious doubt.
