Round 1 · 0:50
Analysts, AI and market side by side. Open a tab for the detail.
The result, the defining moments, and what the verdict means.
Hernandez closed distance behind an overhand left and turned the exchange into a clinch sequence.
He brought the fight to the mat and maintained the front-headlock position as Dumas tried to work free.
Hernandez finished the guillotine at 0:50 of round one for the submission win.
Hernandez arrives 8-0 with every win a finish — five by submission, three by knockout, five of them in the first round — and he is replacing Mickey Gall on nine days' notice after his own Contender Series win on Sept. 15. His path is to close the distance quickly and get to his hands or his back-take before a five-inch reach deficit and a compressed camp become factors.
Dumas, nicknamed "The Reaper," carries a 10-5 record built on finishes — four wins by knockout and two by submission — and now a reach and experience edge over a UFC-debuting short-notice replacement. His task is to use that 79-to-73.5-inch reach advantage and his kickboxing to control range and make Hernandez work from the outside before any grappling exchange develops.
Career stats per UFC.com; recent form is each fighter's last five bouts. Numbers reflect the fighter data snapshot used for this page. Bars compare each stat on a fixed scale; the “Edge” marker flags the leading corner where the gap is meaningful. The snapshot plots five career rates — output, striking defense, durability (strikes absorbed, inverted), takedown defense and finish rate — each normalised on its own scale.
