The Dallas Mavericks are set to open the 2025-2026 NBA season against the San Antonio Spurs on Wednesday, October 22. The Mavericks had the No. 1 overall pick in the 2025 NBA Draft, and the first game of the season marks the regular-season debut of Cooper Flagg.
Dallas will look to take advantage of a clean slate after last year’s midseason trade of Luka Doncic. Flagg has high expectations, especially given the injury to Kyrie Irving, which is expected to sideline him until the start of the 2026 season. Flagg will match up against Devin Vassell for San Antonio, but will likely also see plenty of Harrison Barnes and Victor Wembanyama when he goes down low.
The Sporting News is tracking Flagg’s stats and highlights from his debut.

10:12 p.m. — Flagg’s first field goal attempt was almost an awesome alley-oop from Anthony Davis, but he couldn’t quite get the ball down. Dallas has an early 27-25 lead behind 10 points from Davis, while Wembanyama has eight for San Antonio.

8:15 p.m. — It may be getting lost in the Flagg-Wembanyama matchup, but a reminder: the top two picks in June’s NBA Draft are going head-to-head in their debuts tonight. Dylan Harper vs. Cooper Flagg will become the second time since 1966 that the top two picks in the same NBA Draft will face each other in the first career regular-season game for both players, according to the NBA.
The only other instance was Karl-Anthony Towns (No. 1) vs. D’Angelo Russell (No. 2) in Timberwolves vs. Lakers in October 2015.
8:14 p.m. — Here’s a look at Flagg’s arrival to his first regular season NBA game:

8:12 p.m. — With the Mavericks being without Kyrie Irving to start the season, they’re already handing the offense over to Cooper Flagg. The 6-foot-9 rookie will officially be making his debut listed as the team’s point guard.
Don’t be surprised if the former Duke star initiates Dallas’ offense tonight.
