The finish
Duncan, the British middleweight on a five-fight winning streak, landed the early big shot: he hurt Allen in round one, and a round-two eye poke cost him a point. But Allen kept the pace high, and in the final round he took Duncan down against the cage, worked to his back and locked in a rear-naked choke. Duncan tapped at 2:46. Allen improves to 28-7; Duncan falls to 15-3.
The callout
Allen called out Dricus du Plessis at the post-fight press conference, arguing that the fight is a reasonable ask because the two had previously been expected to meet. The desk found no announcement of a booking, so treat it as a callout, not a matchmaking story.

The rest of the card

Allen Frye Jr. knocked out Harris in round one, Julius Walker finished Gerald Meerschaert with punches in round two, and Loopy Godinez won a unanimous decision over Ketlen Souza. Performance of the Night bonuses of $100,000 went to Allen, Andre Fili, Alice Pereira and Otari Tanzilovi. Outlets differ on a few undercard details, so we list only what is consistent across reports. Our preview has the original card.
The lesson
Duncan landed the first big shot and Allen won the last five minutes. Championship rounds reward the fighter who can still make decisions when tired: a takedown against the cage, a back take, a choke. That is conditioning plus calm, and both can be trained. In your own sparring, finish the last round of every session at full technical quality, not just full effort.
A hurt fighter who stays composed still has the whole fight left.
