The original plan was a basketball. Christian Leroy Duncan, born July 24, 1995, in Gloucester, England, trained hard on the court as a kid and wanted to play in the NBA someday. That’s the detail I keep coming back to, because the guy who ended Eryk Anders with a spinning back elbow was, once upon a time, a teenager in Gloucestershire picturing himself in a completely different arena. Once he finished high school, he went all in on MMA, a sport he’d loved his whole life. Five years after his pro debut, he’s headlining a UFC card.
On Saturday, Oct. 10, Duncan (15-2) meets Brendan Allen in the main event of UFC Fight Night 290. He walks in riding five straight wins. The most recent came over Jared Cannonier, a name that carries weight in any middleweight conversation.
Seven fights, seven wins, one belt
Duncan’s pro career started at Cage Warriors 116 on Sept. 26, 2020, against Kyle McClurkin. He stopped him by TKO in Round 2. Less than three months later he did it again, finishing Lukasz Marcinkowski by TKO in Round 1 at Cage Warriors 119. Then came Will Currie, twice: a Round 2 TKO at Cage Warriors 120 in March 2021, then a unanimous decision in the rematch at Cage Warriors 123 that June. I’d argue the rematch taught him more than the knockout did. Seeing the same man across the cage again and solving him a second time over 15 minutes is a different exam altogether.
His next booking got shuffled around. A fight with John-Martin Fraser moved from Cage Warriors 127 to Cage Warriors 131 in December 2021, Fraser dropped out, and Justin Moore stepped in. Duncan choked him out with a rear-naked choke in Round 1, which matters for anyone who wants to pigeonhole him as a pure striker.
On April 2, 2022, at Cage Warriors 136, he fought Djati Mélan for the vacant middleweight title and won by TKO in Round 3. He defended it in his first try, stopping Marian Dimitrov by TKO in Round 1 at Cage Warriors 146 that November. Cageside Press named him its 2022 Middleweight Prospect of the Year.
Then came the strangest night of his career, and it was a fight that never happened. Duncan was booked against UFC veteran Jesse Taylor at Cage Warriors 148 on Dec. 31, 2022. The day before the event, Taylor was pulled after being involved in a hit-and-run incident. With no fight to take, Duncan used the main card broadcast to reveal that the UFC had signed him, and that his debut would come at UFC 286 in London. Hard to script a better consolation prize.
The UFC years, scars included
The debut was a win on paper and an anticlimax in practice. Duncan faced Duško Todorović at UFC 286 on March 18, 2023, and it ended in Round 1 when a knee injury left Todorović unable to continue. Nobody wants their first UFC victory to come with an asterisk of bad luck, but the official result says TKO, and the record says 8-0.
Three months later, the zero disappeared. Armen Petrosyan beat him by unanimous decision at UFC on ESPN 47 in June 2023. Duncan answered with two finishes in a row: a Round 2 TKO of Denis Tiuliulin (a late replacement for César Almeida) at UFC Fight Night 232, then a Round 1 TKO of Cláudio Ribeiro at UFC Fight Night 238 in March 2024.
The second loss came at UFC 304 in July 2024. Robert Bryczek withdrew and Gregory Rodrigues took the spot, and Rodrigues won a unanimous decision. Both of Duncan’s career losses have come on the scorecards, and that’s worth keeping in mind for the Allen fight. Nobody has stopped him. The two men who beat him found a way to bank more rounds than he did.
What he did after Rodrigues is why he’s headlining now.
The streak
It began quietly, with a unanimous decision over Andrey Pulyaev at UFC Fight Night 255 in March 2025. Then UFC on ESPN 72 on Aug. 9, 2025, and the finish that turned him into a highlight. Near the end of Round 1 against Eryk Anders, Duncan landed a spinning back elbow and followed it with ground and pound for the knockout. It earned him his first Performance of the Night bonus. A spinning back elbow from a 6-foot-something middleweight is a risky shot to throw with the horn approaching, and he threw it anyway. I love that.
Three months later he knocked out Marco Tulio in Round 2 at UFC Fight Night 264, which earned him a second Performance of the Night. MMA Fighting put him on its 2025 Third Team MMA All-Stars.
The two fights in 2026 are the ones that moved him from fun prospect to serious contender. He beat Roman Dolidze by unanimous decision at UFC Fight Night 270 on March 21, then beat Cannonier by unanimous decision at UFC Fight Night 281 on July 18. Neither ended early, and I think that’s the point. The guy who used to fold opponents in the first five minutes now goes three rounds with ranked veterans and leaves with his hand raised. Those are the same 15-minute fights that slipped away from him against Petrosyan and Rodrigues.
Where he stands
Depending on which list you trust, Duncan sits somewhere between 10th and 13th in a crowded division. The Knockout Daily rankings, built on Cagefile data, have him at No. 13 at middleweight. Wikipedia lists him at No. 10 in the Meta UFC middleweight rankings as of Sept. 12, 2026. Either way, he’s in the pack of names one or two big wins from a real title conversation.
The math on his record tells the story. Of his 15 wins, 10 have come by knockout or TKO, one by submission, and four by decision. The decisions are clustering at the top of his résumé, against better opposition, which is exactly how a finisher’s career should evolve.
What’s next
Brendan Allen, Oct. 10, UFC Fight Night 290, main event. Writing in his UFC 332 takeaways for Yahoo Sports, the Stadium Rant writer framed the headliner as two middleweight contenders jockeying for momentum toward title contention, and called the card light on relevance but likely to produce highlight-worthy action. I’ll take the second half of that and push back on the first. A guy who’s won five straight, who beat Cannonier in July, and who’s never been stopped headlining against Allen is plenty relevant to me.
The kid from Gloucester who wanted the NBA got his main event instead. He fights in the last bout of the night on Oct. 10, and a sixth straight win would make him very hard to keep out of the top 10.
