San Antonio Spurs vs Portland Trail Blazers Game 3 Prediction: Wembanyama’s Absence Changes Everything at Moda Center

The NBA playoffs 2026 first round took a dramatic turn when San Antonio Spurs superstar Victor Wembanyama suffered a concussion in Game 2 and is expected to miss Game 3 — possibly Games 4 and 5 as well before clearing protocol. With the series tied 1-1 after Portland’s 106-103 upset in Game 2, the Spurs and Trail Blazers head to Moda Center in Portland for what is now one of the most unpredictable games on the entire playoff slate. Tip-off is set for 10:30 p.m. ET on Amazon Prime Video.

San Antonio entered this series as massive favorites — the Spurs were between -637 and -746 to win individual games in the first two matchups. Without Wembanyama, who is by a wide margin the best player in this series and one of the top five players in the entire league, the Spurs are suddenly navigating unfamiliar territory. Portland, which won the right to this series through the play-in tournament, has now beaten San Antonio once and has the home crowd advantage for the next two games.

From Double-Digit Favorite to Even Money — The Market Has Repriced This Series

The line movement on this game tells you everything. San Antonio opened around -2.5 to -3.5 with Wembanyama’s status in question and has drifted to as close as even money (-118 Spurs, -102 Blazers) as of Friday. The total is set at 220.5, with the over between -105 and -108. The Spurs’ series win probability collapsed from -2000 before Wembanyama’s injury to -550 after it — a dramatic repricing that suggests the entire complexion of this first round has shifted. San Antonio is favored, but Portland is very much alive in a series that two days ago appeared to be a formality.

De’Aaron Fox, Stephon Castle, and the Spurs’ Depth Without Wemby

San Antonio (62-20 regular season) has the best record in the NBA, and they did not get there on the strength of Wembanyama alone. De’Aaron Fox, acquired before the trade deadline, gives the Spurs a legitimate star-level creator who can attack off the dribble, get into the paint, and draw fouls at an elite rate. Stephon Castle has continued his development into a two-way force — his three-point shooting (multiple made threes in each of the first two games of this series) has drawn Portland’s defense out of the paint and opened driving lanes for Fox. Deni Avdija is one of the most versatile small forwards in the West, and his rebounding, defense, and playmaking make him a genuine difference-maker at both ends of the floor.

The question without Wembanyama is whether San Antonio’s supporting cast can manufacture enough efficient offense against a Portland defense that has been genuinely committed in this series. The Trail Blazers held the Spurs to 103 points in Game 2 without Wemby — a figure that would have been unthinkable against a fully healthy San Antonio roster, but is very much achievable against a Spurs team that now leans heavily on Fox and Castle to create.

Portland (42-40) has been fueled by Scoot Henderson, who scored 31 points in the play-in win over Phoenix that earned the Blazers their playoff spot. Henderson has brought that same confidence into this series, and his combination of athleticism and court vision gives Portland a lead guard who can create opportunities for his teammates in transition. Donovan Clingan has been a defensive anchor at center, and Jrue Holiday’s playoff experience brings leadership that this young Blazers team leans on in critical moments. Deni Avdija’s presence as a matchup piece on the wing gives Portland versatility they can use against San Antonio’s varied defensive schemes.

The Trail Blazers have a 22-17 record against the spread as underdogs of 2.5 points or more this season, and at home they have shown they can compete with quality opponents in tightly contested games. The 24-17 home record gives Portland a legitimate edge in a building that will be as electric as Moda Center can get for a playoff game with real stakes.

Wembanyama’s absence is not just about the points he scores — it is about the offensive gravity he commands, the shot-blocking that protects the rim, the defensive rotations that simplify San Antonio’s scheme, and the general psychological pressure he exerts on opponents by simply being the most physically imposing player in any arena. Without him, Portland can attack the basket more freely, draw fouls at a higher rate, and execute a game plan that was genuinely impossible to execute when Wemby was protecting the rim.

Prediction and Best Bet

This is the most intriguing game on the entire Friday slate, and rightfully so. Victor Wembanyama’s absence transforms what should have been a routine Spurs road win into a genuine toss-up where Portland has a real path to the series lead. San Antonio has too much talent in Fox, Castle, and Avdija to fold completely, but playing on the road in a hostile environment without their best player is a tall order. Portland has the crowd, the momentum, and the matchup advantage they needed to level this series.

• Prediction: Portland Trail Blazers 115, San Antonio Spurs 109
• Best Bet: Portland Trail Blazers +2.5 (-109) or moneyline (+120)

Without Wembanyama, the Spurs are a good basketball team that lacks the one component that made them unstoppable. Portland is at home, motivated, and armed with a Scoot Henderson who has already proven he can outperform expectations in a single game. The +120 moneyline for Portland is the best value on the board — a true underdog who has already won once in this series and now plays on their home floor with the most favorable matchup they will get. Back Portland to win outright and send this series in a completely unexpected direction.
