Noche UFC 4 goes down Saturday, Sept. 12, at Desert Diamond Arena in Glendale, Arizona, and the marquee matchup changed twice in the final stretch of fight week. Yair Rodriguez withdrew with a groin injury, and Jose Miguel Delgado — fighting a few miles from home — stepped in against a ranked contender on shortened preparation. The rest of the main card carries its own weight, from a former two-time flyweight champion fighting for his contender status to a pair of top-10 heavyweights. We pulled the sports betting odds from three books open to Canadians as of Wednesday, Sept. 9; all prices are decimal and subject to change as fight week goes on.

No single book leads on every fight here. 1xBet has the best plus-money price on Delgado and Morales, Stake is the standout on the McMillen and Martinez underdogs, and 20Bet posts the shortest favourite prices across the card — useful for anyone laying chalk. The breakdown for each fight follows.
COMPARE NOCHE UFC LINES AT STAKEJean Silva vs. Jose Delgado
Silva entered camp as the No. 6-ranked featherweight and one of the division’s hardest-charging finishers, a reputation built on a 13-fight winning streak that ended only when Diego Lopes landed a spinning back elbow last year in San Antonio. He rebounded with a unanimous decision over Arnold Allen in January and was booked for a ranked step-up against Rodriguez before the injury withdrawal forced this late swap.
Delgado, 28, accepted the short-notice assignment to headline in his own backyard after going 2-0 in 2026 — a narrow decision over Andre Fili followed by a July finish of Austin Bashi. He brings a genuine height and reach advantage, a durable chin and a stated willingness to trade, the profile of a fighter capable of turning a mismatch on paper into a real finish. Silva’s own comments going into fight week suggest the late change hasn’t rattled him: “I’m an athlete. I’m ready to fight… For me, it doesn’t change the opponent. I’m there to fight, and I’m going to fight.”
Every book agrees Silva is the clear favourite, but the gap between 1.22 and 1.23 is thin enough that price should decide: 1xBet’s 1.23 is the best number on the favourite, and its 4.05 on Delgado still beats Stake’s plus-money underdog price once vig is considered against 20Bet’s shorter 4.10 line. For anyone chasing the biggest payout on the upset, Stake’s 4.30 leads the market.
Prediction: Silva by TKO, Round 2. Pick: Silva 1.23 (1xBet).
Brandon Moreno vs. Joseph Morales
The co-main is its own story. Moreno, a two-time former flyweight champion, is 4-5 in his last nine fights and facing real questions about his contender status at 32. Morales, the TUF 33 winner, carries momentum from a run of recent finishes into his first meaningful step up, and the market has quietly installed him as the favourite — 1xBet has Morales at 1.80 with Moreno out to 2.02, while Stake is the most conservative book on the underdog price at 2.00.
Prediction: Morales by decision. Pick: Morales 1.75 (20Bet).
Manon Fiorot vs. Alexa Grasso
Fiorot is 8-1 inside the Octagon with a résumé that arguably deserved a title shot before the division’s recent shakeup left her on the outside. Grasso, a former flyweight champion, is fresh off what has been called the most brutal finish of the year against Maycee Barber and remains live against anyone at 125 pounds. 20Bet has the shortest number on Fiorot at 1.37; Stake’s 3.00 is the best plus-value price for anyone backing the former champion.
Prediction: Fiorot by decision. Pick: Fiorot 1.37 (20Bet).
Waldo Cortes-Acosta vs. Curtis Blaydes
Two top-10 heavyweights meet, with Cortes-Acosta (No. 7, 10-3 inside the Octagon) looking to bounce back from a decision loss to Alexander Volkov against a decade-long divisional stalwart in Blaydes. The number barely moves across books — 1.43 to 1.49 on the favourite — making this one of the more efficiently priced fights on the card. 20Bet’s 1.43 is the best price to lay; Stake’s 2.65 is the top number on the live underdog.
Prediction: Cortes-Acosta by decision. Pick: Cortes-Acosta 1.43 (20Bet).
BACK YOUR ROUND PROP AT 29BLACKTommy McMillen vs. Marwan Rahiki
Both fighters came through DWCS Season 9 and are being pushed as the division’s hottest prospects. McMillen, 28 and unbeaten across 18 pro and amateur fights, trains locally near Phoenix; Rahiki arrives from Sydney unbeaten with back-to-back stoppage wins. 1xBet has the shortest number on McMillen at 1.62, while Stake offers the best plus-money price on Rahiki at 2.41.
Prediction: McMillen by decision. Pick: Rahiki 2.41 (Stake).
David Martinez vs. Dan Ige
Martinez, an ascending DWCS alum on a two-fight decision streak, opens as the heaviest favourite on the main card against Ige, a featherweight veteran making his first drop to bantamweight after going 0-4-1 in his last five. Stake’s 4.10 is the best number on the underdog by a wide margin over 20Bet’s 3.68; Martinez backers should take 1xBet’s 1.27.
Prediction: Martinez by decision. Pick: Martinez 1.24 (Stake or 20Bet).
Noche UFC Best Bets for Canadian Bettors
Silva 1.23 (1xBet) — A ranked, momentum-carrying finisher against a short-notice replacement stepping up two levels. The crowd noise favours Delgado; the number should still favour Silva.
Morales 1.75 (20Bet) — Moreno is 4-5 in his last nine fights, and the market has made the TUF winner a live favourite. That’s a signal worth respecting.
Fiorot 1.37 (20Bet) — An 8-1 Octagon record against a former champion who hasn’t fought at Fiorot’s pace in some time.
Rahiki 2.41 (Stake) — Two unbeaten prospects meet, and the extra plus-money value sits with the visiting Australian.
