How to watch NBA Finals 2024: live stream Boston Celtics vs Dallas Mavericks game 3 online

With a record breaking 18th NBA Championship in their sights, the Boston Celtics have leapt into a 2-0 lead in the 2024 Finals as the action now heads to the Lone Star State to the Dallas Mavericks' home court. The best team in the country will take some stopping from here and we're here to help with all the information you need to watch NBA Finals live streams of the Celtics vs Mavericks, with Sling TV showing every minute in the US.

NBA Finals 2024 preview: Boston Celtics vs Dallas Mavericks

Each having made it through to the Finals in relative comfort – the Celtics have lost only two games on the way through the postseason, to the Mavs' five – it now comes down to a best-of-7 series.

Brad Stevens's Boston side started as favorites, having booked their NBA playoffs spot way back on March 14 and confident of ending their 16-year hoodoo. Jaylen Brown and Kristaps Porziņģis started things off in the perfect way for the Celtics, each recording 20 points in a crushing game 1 win at TD Garden by 107 to 89. Game 2 was an edgier, although still comfortable 105-98 win for the Celtics.

The Texas franchise will be desperate to bounce back – and fast. They only have to look back into recent history and the 2021 Milwaukee Bucks overturning a 2-0 deficit to run out as champions. Luka Dončić managed 30 and 32 points respectively in the first two games (the second the first triple double ever for the franchise in the Finals). The Slovenian ace has a busy couple of months ahead, with qualification games for the Paris 2024 Olympics following hot on the heels of the NBA Finals. If it's going to be golden year for the future Hall of Famer, he'll need his teammates to step up to the plate when the action reaches the American Airlines Center.

Whether you're a b-ball nut or a casual fan, the NBA Finals are an annual cause to flick on the action and watch the threes rain down. To see how the Boston Celtics vs Dallas Mavericks series plays out, be sure to follow our guide to watch NBA Finals 2024 live streams – no matter where you are in the world.
