UFC Paris Preview: Imavov–Borralho headlines, Saint-Denis–Ruffy

The UFC’s annual trip to Paris for UFC Paris returns to a fever-pitch Accor Arena with a main event that could redraw the middleweight title queue: hometown ace Nassourdine Imavov takes on Brazil’s surging Caio Borralho. In the co-main, France’s Benoît “God of War” Saint-Denis welcomes the rapid rise of knockout artist Mauricio Ruffy, a matchup built for noise, drama, and violent momentum swings. The card is set for Saturday, Sept. 6, with prelims and main card airing on ESPN+.

Why this night matters

Four straight years of sellouts have turned Paris into a real MMA hotbed with UFC Paris, and the UFC has leaned into that energy with French favorites at the top of the bill. Imavov–Borralho is more than a showcase: with middleweight in flux and new contenders jostling for pole position, the winner places themselves within touching distance of a title discussion. Meanwhile, Saint-Denis gets a critical chance to steady his climb at lightweight, but he must do it against one of the division’s most dangerous new faces in Ruffy.

Main event: Nassourdine Imavov vs. Caio Borralho

Imavov, a 6’3″ technician who thrives at mid-range, built his name on clean shot selection, length management, and sneaky counters off the lead hand. His breakthrough wins pushed him near the top of the rankings and earned him another spotlight in his adopted home city. Borralho, the southpaw from Fighting Nerds, packages composed kickboxing with well-timed level changes and fence control—he wins minutes with discipline and makes opponents pay for over-committing. Their physical dimensions and measured styles suggest a tense, tactical fight with sudden-swing potential.

Tactics to watch. Expect an early battle over lead-hand control and outside foot position (orthodox vs. southpaw). Imavov’s best work often appears when he establishes the jab to draw counters, then steps in behind straight rights and uppercuts as opponents retreat. For Borralho, the A-plan is to disrupt rhythm—jab to the chest, low calf kicks to slow entries, then mix in takedown threats to park Imavov on the fence, where short elbows and knees can accumulate. If Borralho repeatedly wins the clinch entries, he chokes off Imavov’s reads; if Imavov keeps the fight at range and punishes the first layer of shots, the Brazilian’s entries become riskier.

Form and stakes. Both men enter Paris on strong form against ranked opposition, with Borralho putting together a long unbeaten run in the UFC and Imavov scoring signature results that vaulted him up the ladder. The chatter around this matchup has consistently framed it as an eliminator or near-eliminator, depending on champion scheduling. Treat the stakes as “title conversation next” rather than a guaranteed shot—either way, five rounds in Paris should produce clarity at 185.

The mind-game subplot. In the build-up, Imavov openly acknowledged some gamesmanship: bowing out of a backup role to force Borralho into a difficult weight-cut scenario ahead of their headliner, a move he and his team framed as deliberate strategy. It’s a spicy wrinkle—worth noting without over-selling—because repeated cuts can affect pace and resilience. Whether it matters after the first exchange is anyone’s guess, but it adds edge to a fight already simmering.

Keys to victory.

• Imavov: Work behind feints, win the lead-hand duel, punish exits with the long two, and make the cage big—reset instead of clinching.
• Borralho: Double-threat sequences (strike-to-shot), chain wrestle on the fence, and tax Imavov’s stance with kicks to blunt counters. (Profiles and past fights back these tendencies.)

Co-main: Benoît Saint-Denis vs. Mauricio Ruffy

Saint-Denis is everything his nickname promises: pressure, persistence, and a willingness to walk into fire to drag a fight where he wants it. The Frenchman’s best nights weave together clinch-to-takedown sequences, punishing ground-and-pound, and a submission threat that forces hurried scrambles. Across from him is Brazil’s Mauricio “One Shot” Ruffy—one of 2025’s breakout names—who combines keen shot selection with genuine dynamite. He has the kind of finishing confidence that changes how opponents enter exchanges.

Ruffy’s highlight reel already includes a wheel-kick finish that earned “KO of the Year” chatter, plus main-card wins that proved he isn’t just a fast starter. His UFCStats profile underlines the efficiency: strong significant-strike output with high accuracy. The danger for Saint-Denis is obvious—reckless pocket entries get punished—but the Frenchman can flip the script if he makes Ruffy fight through underhooks, mat returns, and shoulder-to-jaw clinch pressure for long stretches. That kind of attrition forces a striker to spend energy on standups instead of setups.

Footwork and fence craft. BSD must corner with his feet, not just his hands: step outside, cut the lane, and make Ruffy circle toward the power side into level-change traps. Ruffy, by contrast, should aim for first-layer takedown denial, pivot escapes, and counter-body work to sap the Frenchman’s chain-wrestling. If Ruffy keeps the fight at his preferred distance for two rounds, he can start calling his shots; if Saint-Denis turns it into a clinch-heavy grinder early, the crowd might get that trademark late surge. (ESPN’s fighter pages and Tapology listing confirm the matchup as the co-main.)

Atmosphere, timing and viewing

Accor Arena has become a genuine home-field amplifier for French talent and UFC Paris. Expect a thunderclap reception for both Imavov and Saint-Denis, with every feint and forward step drawing roars. Broadcasters list prelims beginning in the early afternoon U.S. time and the main card in mid-afternoon, with ESPN+ carrying both slates; always double-check on fight day for any shuffle.

What a win means

Imavov or Borralho: A decisive, five-round performance in Paris should translate to title-shot proximity—if not an outright No. 1 contender tag—depending on the champion’s calendar. With middleweight’s recent upheavals, the matchmakers will be watching closely.

Saint-Denis: Beating a streaking knockout threat steadies his push back toward the top 10 and reinforces the blueprint that made him a cult favorite.

Ruffy: A marquee win over France’s standard-bearer would rocket him from “can’t-miss prospect” to genuine ranked menace overnight—and in hostile territory, no less.

Final read

This Paris card is built on tension between discipline and danger. In the main event, Borralho’s structure tries to smother Imavov’s sharp, opportunistic counters; in the co-main, Ruffy’s sudden violence meets Saint-Denis’ suffocating pace. However it breaks, the Accor Arena is likely to feel less like a venue and more like a pressure cooker—and by the time the lights go up, we should have a clearer picture of the roads to gold at 185 and the next wave of threats at 155. Tune in early; the sound you hear might be a title conversation snapping into place.
