Christian Leroy Duncan isn’t rewriting his plans. The No. 10-ranked UFC middleweight posted a short statement on Instagram after Brendan Allen submitted him in Round 5 of the UFC Vegas 122 main event Saturday night (Oct. 10, 2026) at Meta Apex in Las Vegas.
“Thankful for the experiences that carry us forward,” Duncan wrote. “Nothing changes. The fire is too bright to dampen. The pursuit continues. Back to work.”
That’s a calm message from a man who had just been stopped for the first time as a professional. MMA Mania reported the post and noted that the loss ended a five-fight winning streak that had pushed Duncan into the middleweight top 10.
How it got there
Allen told everyone what his plan was before fight week ended. He warned Duncan that he “better catch me early,” and the idea was simple: drag the British striker into the late rounds and see what was left. Duncan didn’t fold. He stayed competitive into the championship rounds, but Allen’s experience, durability and grappling wore on him until “All-In” got the finish in Round 5. Allen was the more experienced man in a 25-minute fight, and that’s how he won it.
The streak Duncan put together is still worth respecting. He beat former title challenger Jared Cannonier. He beat Roman Dolidze at The O2 in London on March 21, 2026. Before that he knocked out Marco Tulio and Eryk Anders, and both finishes were the kind that end up in highlight reels. Even after Saturday he’s 8-3 inside the Octagon, and at 31 he’s still one of the scariest strikers at 185 pounds.
What’s next
There’s no booking yet. Losing a main event to a ranked grappler usually means taking a step back in the rankings next time out, and MMA Mania suggested Roman Kopylov as an opponent. Two strikers who would both rather settle it on the feet than on the mat? I’d watch that, and I suspect the judges would never be needed.
Quick take
I like the post, and I like even more that it said nothing about the grappling being boring or unfair. Allen won the way he said he would. Duncan has three rounds’ worth of evidence that his hands work at this level, and two rounds’ worth of evidence about what happens when a durable wrestler is still pushing in minute 21. The fix comes from the camp, not from Instagram: more live grappling rounds when he’s already exhausted, better get-ups, and a gas tank built for 25 minutes and not 15. If he comes back against someone like Kopylov and spends the second half of that fight on his feet and in control, this loss turns into tuition. If he comes back looking exactly the same, nothing changes will mean something he didn’t intend.
