Allen faces Duncan in UFC Fight Night 290 main event Saturday

Duncan's reach and discipline could keep Allen from the canvas
Allen's wrestling is his primary weapon, but Duncan's four-inch reach advantage gives him the tools to fight at distance and avoid the takedown.

So we have Allen coming in hot with three straight wins, but Duncan is the betting favorite despite nearly even odds. What's the disconnect?

Mimi

It's about what each fighter does best. Allen wins by getting you down and submitting you or controlling you on the mat. Duncan wins by keeping you at distance and outstriking you. The reach advantage and the striking numbers give Duncan the tools to avoid Allen's strength.

But Allen has won three straight. How much of that momentum should we weight against Duncan's five-fight streak? The source doesn't really tell us how recent Duncan's wins are or how dominant they were.

Mimi

Fair point. Duncan's last fight was July 18, so it's been a few months. Allen fought in June. But the quality of opposition does seem to favor Duncan—Cannonier, Anders, Dolidze are all names with real pedigree.

Mark

If Allen gets Duncan down, what happens?

Mimi

That's the whole fight. Allen's submission average is 1.06 per outing. He's a threat on the ground. But Duncan has to avoid that scenario entirely, which means staying upright and using that four-inch reach.

Luke

The striking accuracy gap is interesting—Duncan at 63.95%, Allen at 58.87%. But we don't know if that's because Duncan is more precise or because he's fighting at a distance where he can be more selective. Context matters.

Mark

So the prediction is Duncan by decision?

Mimi

Yes, if he's disciplined. The plus-130 odds on the fight going the distance is attractive because both fighters have shown they can go deep into fights without finishing.

Luke

Which means the real bet might not be on who wins, but on how long it lasts. The market seems to think a finish is more likely than not, but the fighters' histories suggest otherwise.

  • Allen enters with three straight wins but faces a Duncan who has beaten more dangerous men and holds a four-inch reach advantage that could keep the fight exactly where Allen doesn't want it.
  • The betting market refuses to pick a clear winner, with odds so close to even that the oddsmakers themselves seem to be watching with genuine uncertainty.
  • Allen's entire game plan depends on closing distance and dragging Duncan to the canvas — a strategy that is sound on paper but demands he first survive Duncan's striking volume and accuracy.
  • Expert consensus tilts toward Duncan winning a decision if he maintains discipline and keeps the bout upright, but the plus-130 odds on a distance fight suggest the smarter money may be on neither man finishing the other.
  • For the bold, Duncan by decision pays plus-450 — a number that quietly acknowledges how much can go wrong before anything goes right in a fight this evenly matched.

In the desert lights of Las Vegas, two middleweight fighters meet Saturday night carrying the weight of their respective journeys — Allen with his wrestler's instincts and hard-won momentum, Duncan with his longer reach and a streak built against stiffer opposition. UFC Fight Night 290 offers not a clash of giants but something more quietly compelling: a near-even contest where the margin of victory may hinge on a single takedown or the discipline to deny one. It is the kind of fight that reminds us how fine the line is between a fighter's strength and his vulnerability.

Brendan Allen and Christian Leroy Duncan meet Saturday night in Las Vegas as the main event of UFC Fight Night 290, a five-round middleweight bout that begins at 8 p.m. Eastern on Paramount+. It is a matchup of contrasting styles and nearly identical odds.

Allen brings a 27-7 record and three consecutive wins, most recently a unanimous decision over Edmen Shahbazyan. He is a fighter who tends to go the distance — five of his last six fights have reached the judges — with his lone recent finish coming via fourth-round knockout of Reinier de Ridder. Duncan, at 15-2, is riding five straight victories, including a first-round knockout of Eryk Anders and a decision over Roman Dolidze, opponents considered more formidable than most on Allen's recent résumé.

The physical edge belongs to Duncan in measurable ways: a four-inch reach advantage, more strikes landed per minute, and superior striking accuracy. Allen's counter is the ground game — he averages 1.52 takedowns per fight and attempts submissions at a meaningful rate. His path to victory is clear, if narrow: get Duncan down and keep him there.

The moneyline sits at Allen minus-115, Duncan minus-105 — essentially a coin flip with a slight lean. Experts favor Duncan by decision, reasoning that his reach and striking discipline can neutralize Allen's wrestling if he manages distance. The fight going the distance pays plus-130, a number that reflects both fighters' recent tendencies to see the scorecards. For those seeking a larger return, Duncan by decision or technical decision is available at plus-450.

Brendan Allen and Christian Leroy Duncan will square off Saturday night in Las Vegas for the main event of UFC Fight Night 290, a five-round middleweight contest that pits two fighters with sharply different strengths against each other. The prelims start at 5 p.m. Eastern time, with the main card kicking off at 8 p.m. Eastern on Paramount+, all taking place at the Meta Apex.

Allen arrives with momentum on his side. His record stands at 27 wins and 7 losses, and he has won three fights in a row. Most recently, he earned a unanimous decision over Edmen Shahbazyan on June 6. Over his past six outings, he has gone the full distance in five of them, winning three and losing two. His only finish in that stretch came in October 2025, when he knocked out Reinier de Ridder in the fourth round of a Fight Night main event. Duncan, by contrast, carries a 15-2 record and is riding a five-fight winning streak. He most recently defeated Jared Cannonier by unanimous decision on July 18. Among his recent wins are a first-round knockout of Eryk Anders and a decision victory over Roman Dolidze—opponents who, on paper, represent stiffer competition than some of Allen's recent foes.

The physical matchup favors Duncan in certain measurable ways. Both men stand six feet two inches tall, but Duncan possesses a four-inch reach advantage. He also lands significantly more strikes per minute—4.45 compared to Allen's 3.75—and does so with greater accuracy, posting a 63.95% significant strike accuracy rate versus Allen's 58.87%. Where Allen holds the edge is on the ground. He averages 1.52 takedowns per fight with a 41.07% success rate, and he attempts submissions at a rate of 1.06 per outing. His path to victory runs through getting Duncan to the canvas and keeping him there.

The betting market treats this as nearly even. Allen sits at minus-115 on the moneyline, meaning a bettor would need to wager $115 to win $100, while Duncan is at minus-105, requiring a $105 bet to win $100. The oddsmakers are split on whether the fight finishes early or goes the distance. The over on 3.5 rounds sits at minus-120, the under at minus-110. When asked whether the bout will go the full distance, the yes side offers plus-130 odds, while no pays minus-180.

Expert analysis favors Duncan, though the margin is narrow. The reasoning centers on Duncan's reach and his ability to control the fight at distance. If Duncan can keep Allen at arm's length and prevent the takedown, he can dictate the pace and likely secure a decision. Allen's wrestling prowess is real, but it only matters if he can close the gap and execute. The consensus pick leans toward Duncan winning by decision if he maintains discipline and keeps the action upright. Some analysts suggest betting on the fight going the distance at plus-130 odds, given that Allen has reached the judges' scorecards in five of his last six fights and Duncan has needed a decision in four of his past six bouts. For those willing to take a bigger swing, Duncan by decision or technical decision pays plus-450, offering a chance to multiply the initial wager by 4.5 times.

If Duncan can push Allen away, keep the fight upright, and avoid extended time on the mat, he'll be in good shape
