How to Watch Celtics vs Spurs

The Boston Celtics hit the road to face the San Antonio Spurs in a highly anticipated cross-conference showdown. Both squads enter Tuesday night riding the momentum of recent victories. Boston recently took down the Cavaliers behind Jaylen Brown’s stellar play, while San Antonio is fresh off a decisive blowout victory over the Rockets, where Victor Wembanyama dominated the floor.

Tip-off is scheduled for 8:00 PM EST on Tuesday, March 10, 2026, at the Frost Bank Center. Broadcast coverage will be available nationally on NBC and Peacock, with local broadcasts airing on NBCS-BOS and FDSSW. From a betting perspective, the market will be keeping a close eye on the star-studded individual matchups. The Celtics enter as formidable road underdogs, boasting an elite duo of Jayson Tatum and Brown, but they face a live home favorite powered by Wembanyama and De’Aaron Fox. With both franchises showing strong recent form, finding the betting edge requires looking beyond the surface and analyzing the pace of play.

Celtics vs Spurs Odds

Odds as of March 10, 2026, at 2:36 PM ET from BetMGM.

The oddsmakers at MGM have the host Spurs as 3.5-point favorites. This tight spread, accompanied by a moderate game total of 221.5 points, indicates the market expects a hard-fought, defensive battle. Interestingly, both the spread and the total have remained completely stagnant since the initial lines were released. The total lack of line movement across the board suggests bookmakers feel incredibly confident in their opening numbers, even with heavy public money backing the Over and the home favorites.

If we strip away the sportsbook’s built-in vigorish from the moneyline odds, we can determine the normalized win probabilities. Calculating the vig-free implied odds, San Antonio holds a 60.78% probability of defending their home court. Meanwhile, Boston has a 44.4% chance of securing the outright upset, with the percentages summing to 100%.

For bettors looking to attack the straight moneyline market, a standard $20 wager yields vastly different returns. A $20 bet on the favored Spurs at -155 odds generates a profit of $12.90, resulting in a total payout of $32.90. Conversely, taking a shot on the underdog Celtics at +125 with that same $20 stake returns a $25.00 profit, making for a total payout of $45.00 if they successfully pull off the road victory.

BOS vs SAS Injury Reports

Heading into tonight’s primetime clash, both teams are navigating notable rotational absences that could heavily influence half-court execution.

Having undergone surgery just a few days ago (March 7) to stabilize a fractured right ring finger, Nikola Vučević is sidelined for the next 3-to-4 weeks. Without his interior presence, Boston will be severely tested by San Antonio’s massive front line. Bettors should anticipate smaller, quicker lineups to pull Wembanyama away from the basket. On the other side, ruling out Harrison Barnes poses a schematic headache. Without him, the perimeter defense will have to dig deep into the bench to find players capable of switching onto elite opposing wings.

Celtics vs Spurs Picks

While pre-game narratives naturally lean toward the star power of the defending Eastern Conference powers, digging into the situational data points toward tremendous value on the road underdogs and a defensive battle. Here’s our breakdown of the best ways to attack this cross-conference showdown.

The Spread: Celtics +3.5 (-110 at BetMGM)

Taking the points with Boston is arguably the most glaring value on the board tonight. They have been absolute warriors when catching points, boasting a staggering 10-2 (83.3%) record against the spread as underdogs over their last 12 games. The trend becomes even more incredibly pronounced away from home, as they are 8-1 (88.9%) ATS on the road as underdogs over their last nine contests. The public handle reveals that 66.0% of the total spread stake is backing San Antonio to cover. By taking the points, we are playing a profitable contrarian position. Furthermore, Boston elevates their game against quality competition, going 5-1 (83.3%) straight up against opponents with a winning record in their last six matchups. Fading them in this specific underdog spot is historically a losing proposition.

The Total: Under 221.5 (-115 at DraftKings)

If you are looking for a high-flying shootout, look elsewhere. The Boston offense operates at an incredibly methodical speed, ranking dead last in the NBA with just 94.7 possessions per 48 minutes. By deliberately slowing the game down, they limit variance and maximize their half-court execution against a defense that ranks 3rd in Defensive Rating (108.3). Boston sits right behind them at 5th in Defensive Rating (109.5) while allowing a league-low 106.9 points per game. When these two specific franchises clash, the defensive intensity traditionally ramps up. The Under has hit in five of the last six matchups (83.3%). Despite a massive 88.2% of the financial handle backing the Over, the historical data and San Antonio’s recent macro trends—where the Under has hit in 20 of their last 30 games (66.7%)—make fading the public the most logical play.

Best Player Prop: De’Aaron Fox Over 5.5 Assists (-150 at BetMGM)

Because the game will largely be contested in the half-court, taking care of the basketball is paramount. Both teams share an identical, elite 2.0 Assist-to-Turnover ratio. For the home team, half-court facilitation falls squarely on De’Aaron Fox’s shoulders. Transition opportunities might be limited by elite drop coverages. Fox will have the ball in his hands constantly. He will be tasked with methodically dissecting the perimeter and feeding Wembanyama in the pick-and-roll to puncture a stingy defense. The Over is juiced to -150 across the market, indicating strong, sharp agreement that he will clear this highly probable playmaking floor.
