BREAKING NEWS: Mavericks Co-Owner Miriam Adelson Suspends Coach Jason Kidd Over Banned Substance Violation

In a stunning and unexpected development, Dallas Mavericks co-owner Miriam Adelson has reportedly suspended Head Coach Jason Kidd from all team activities following a positive test for a banned substance, sources close to the organization confirmed early Tuesday morning.

The test, which was administered as part of an internal compliance check reportedly linked to new NBA health protocols, returned results late Monday evening. According to initial reports, the substance in question has not yet been publicly disclosed, but league insiders suggest it falls under the NBA’s list of performance-affecting or prohibited lifestyle substances.

Official Statement Pending

As of now, neither the Mavericks nor Jason Kidd has released an official statement. However, team sources indicated that Miriam Adelson, who became the controlling stakeholder in the Mavericks after acquiring majority interest in 2023, took immediate action upon receiving the report.

“This is a matter of integrity and accountability,” a source within the Mavericks front office stated under condition of anonymity. “Ms. Adelson has made it clear from day one that professionalism and adherence to league standards are non-negotiable. This isn’t just about one test—this is about the reputation of the organization.”

Impact on the Team

With the preseason just weeks away, Kidd’s sudden removal from team activities could send shockwaves through the Mavericks’ preparation for the 2025-26 NBA season. Kidd, who has served as the team’s head coach since 2021, was a key figure in the development of the team’s young core and playoff strategy.

Assistant coach Jared Dudley is expected to take over interim coaching duties while the organization awaits further clarification and league guidance.

League Response Anticipated

The NBA has yet to comment officially, but sources within the league office have confirmed that the matter is “under review” and that any potential disciplinary action will depend on the outcome of additional testing and investigation.

A league insider told The Sporting Ledger, “We take these matters seriously, especially when it involves leadership personnel. The NBA’s substance policies apply to everyone, not just players.”

Speculation and Reactions

Fans and analysts alike have taken to social media to express their shock and confusion. Reactions have ranged from supportive to speculative, with many questioning the timing and circumstances of the incident.

Sports analyst Stephen A. Smith said on ESPN’s First Take, “If this is true, this is a massive blow not just for Jason Kidd, but for a Mavericks franchise that’s trying to build a culture of excellence and win now. You can’t have this kind of thing creeping into your locker room weeks before the season.”

What’s Next?

Pending results from a follow-up investigation, Jason Kidd’s future with the franchise remains unclear. If the initial findings are upheld, the Mavericks may face the difficult decision of terminating the head coach’s contract—a move that would send ripple effects across the NBA.

Miriam Adelson, known for her high-profile involvement in both business and philanthropy, has reportedly taken a personal interest in the matter and is expected to address the media later this week.
