NBA Opens 2026 Season With Three Marquee Matchups

The NBA begins its 2026-27 season on Tuesday, October 20, with three nationally featured matchups showcasing major roster changes and a rematch of last season's Western Conference Finals. The Boston Celtics face the Detroit Pistons, the defending champion New York Knicks host the Philadelphia 76ers, and the Oklahoma City Thunder visit the San Antonio Spurs. According to the schedules announced by Sportsnet and SiriusXM Canada, the Celtics-Pistons game starts at 3 p.m.

ET, followed by the Knicks-76ers matchup at 7 p.m. ET and the Spurs-Thunder contest at 9:30 p.m. ET.

Sportsnet and Sportsnet+ will carry the tripleheader, while SiriusXM NBA Radio will broadcast all three games. The opening slate highlights the impact of an eventful offseason, including a blockbuster trade between Boston and Philadelphia, adjustments to the Thunder's supporting cast, and the Knicks' attempt to defend their championship.

Boston enters the season with Jayson Tatum continuing his return after an Achilles tear. Sportsnet identifies the Celtics as title contenders, citing their depth and Tatum's expected role as the team begins a campaign that opens against a Detroit side seeking a stronger response after its second-round playoff exit.

The Pistons also enter the season following an offseason contract dispute involving star center Jalen Duren. The opening game against Boston offers both teams an early opportunity to establish momentum, according to Sportsnet's season preview. The Celtics' roster changed significantly during the offseason when the team traded All-Star Jaylen Brown to Philadelphia in a deal centered on Paul George. The move reshaped both teams and added another major storyline to the season's opening night.

At Madison Square Garden, LeBron James is set to make his Philadelphia 76ers debut as the Knicks raise their championship banner. Philadelphia's new-look lineup also includes Brown, Joel Embiid, Tyrese Maxey and VJ Edgecombe, leaving coach Nick Nurse with the task of integrating several prominent players. New York enters the campaign after winning the NBA title with a 16-3 postseason record, according to Sportsnet. The Knicks have largely retained their championship roster, although backup center Mitchell Robinson departed for Boston and former 76ers center Andre Drummond joined New York as his replacement.

The final game features the Thunder and Spurs, who meet for the first time since San Antonio defeated Oklahoma City in last season's Western Conference Finals. Both teams remain among the leading contenders in the conference, according to Sportsnet's preview. Oklahoma City made several salary-cap-related roster changes, parting ways with Canadian guard Lu Dort and rotation players Isaiah Joe and Aaron Wiggins.

The Thunder will look to younger players, including Cason Wallace and Aday Mara, to help replace the departed contributors as they pursue another trip to the NBA Finals. San Antonio, meanwhile, added veteran wing Tobias Harris from Detroit while continuing to rely on its young core, including Dylan Harper and Stephon Castle. The Spurs defeated Oklahoma City in four of their five regular-season meetings last season and also won their seven-game playoff series.

The Spurs will begin the new campaign seeking to build on that success after losing the NBA Finals in five games last season. The matchup against Oklahoma City provides an early test of both teams' championship ambitions.

Beyond the opening tripleheader, SiriusXM Canada announced that it will broadcast every NBA game from the regular season through the NBA Finals. The company said listeners using its app or vehicles equipped with its latest-generation 360L radios can access both home and visiting team broadcasts for every matchup. SiriusXM NBA Radio will also provide daily basketball discussion and analysis throughout the year, featuring former players, coaches, executives and other league experts. The network prepared preview programs covering all 30 NBA teams ahead of the season, with those shows available on demand through the SiriusXM app.
