Arman Tsarukyan vs Mauricio Ruffy: a title shot, and the one way to beat the knockout artist

Arman Tsarukyan headlines the UFC 331 co-main against Mauricio Ruffy on September 19 in Los Angeles, and the winner is next in line for the lightweight title. Tsarukyan (23-3) is one of the division’s elite wrestlers, back after a layoff and openly hunting a quick finish. Ruffy (14-2) is the flashiest knockout artist at 155, with one glaring clue in his record about how this fight can go wrong for him.

Key takeaways

Arman Tsarukyan is one win from the title he already chased

The most avoided man at 155 returns

Tsarukyan has spent years as the lightweight nobody at the top wanted, an elite wrestler with the grappling to drown contenders and enough power to hurt them standing. He was once a step from the belt before the plan fell apart, and this is his road back: beat Ruffy and the next fight is for the title. Making his first walk since last November, he is not treating the co-main as a tune-up.

He also wants it over fast, and for a reason that is hard not to like. Tsarukyan has said he does not need the full 25 minutes and would rather finish quickly so his father, watching from home, does not have to sit through a long, nervous night. A wrestler with a personal deadline is a dangerous thing for a striker who needs deep water.

Why this fight, now

The UFC did not hand him a stay-busy opponent. Ruffy is a real threat, which is exactly why beating him means something: a dominant win over a dangerous finisher is a cleaner title argument than another grind over a gatekeeper.

Mauricio Ruffy and the blueprint against him

A knockout artist with one clear leak

Ruffy (14-2) is one of the most exciting finishers the UFC has, with 13 of his 14 wins by knockout and a highlight reel that already includes UFC stoppages of Michael Chandler, Rafael Fiziev and King Green. On the feet he is a nightmare, fast and creative, the kind of striker who ends a night with a single sequence. If this stays standing for long, it is his fight.

But the record leaves a blueprint. Ruffy’s only UFC loss came when Benoit Saint Denis took him down and submitted him in Paris — outgrappled, not outstruck. Against the best wrestler he has ever faced, the central question is not whether Ruffy can hurt Tsarukyan, but whether he can stay off his back long enough to try. Ruffy is unbothered by the noise. “Anyone can talk,” he said, “the actions do the talking,” and he called Tsarukyan the toughest challenger in the division.

The stylistic read

This is wrestling versus knockout power in its purest form. Tsarukyan wants the level change, the mat and the elbows; Ruffy wants space and one clean shot. Whoever imposes his fight in the first five minutes usually decides where the other 20 go.

Round 3 stoppage via TKO. Elbows, elbows – cut his face.

What the winner walks into

A title shot on hold until 2027

The stakes stretch past this card. Lightweight champion Justin Gaethje is out until 2027 with injury, which means the Tsarukyan-Ruffy winner does not fight for the belt right away, but becomes the man in waiting for it. That turns a co-main into a genuine title eliminator, and it is why both men are treating September 19 like a championship night in everything but name.

For Tsarukyan it is the redemption of a title run that stalled. For Ruffy it is the leap from highlight machine to true contender. Neither can afford a flat performance with a 2027 belt this close, which is exactly what makes this the fight to watch beneath the main event.
