Every disputed call that sent a crowd into a frenzy, every replay review that dragged on while coaches paced the sideline: the NBA is quietly building infrastructure that could eventually address both. The league is running two parallel technology experiments in select preseason exhibition games, using Wilson connected basketballs with embedded Bluetooth sensors and wrist-worn devices that let referees communicate directly with the NBA Replay Center.
The ball data is strictly for research purposes, according to ESPN reporting. Neither experiment is cleared for the regular season.
The Ball That Knows Things
Wilson’s sensor-equipped basketball enters the NBA lab for research-only data collection.
Wilson has prior history with sensorized basketballs, previously marketing a consumer product that tracked shooting performance via Bluetooth and a paired smartphone. The NBA trial uses the same embedded-sensor concept, but the league has not publicly confirmed the full data set, sensor configuration, or accuracy thresholds being applied.
The available reporting describes prospective officiating applications but does not confirm a specific list of data points the ball will capture. Any future application to live officiating would require proven reliability and clear rules about when sensor data informs or overrides human judgment. None of that framework exists yet.
The Wristband in the Striped Shirt
On-court officials get a direct line to the Replay Center, built for scoring corrections and clock problems.
The wrist wearables are narrower in scope and further along in testing. Officials in select preseason games will use the devices to communicate with the Replay Center during designated situations, including replay reviews, scoring changes, and clock malfunctions.
The NBA described a prior pilot during the 2026 Summer League as successful, according to ESPN reporting. The stated goal is faster, more direct coordination with replay officials, not automated decision-making.
What This Is, and What It Isn’t
No deployment timeline, no confirmed game list, and no rule changes: this is infrastructure testing.
The NBA has not disclosed which exhibition games will use either technology, how many officials will participate, or when a broader deployment decision might come. Regular-season use is not planned at this stage.
The league is building an evidentiary case before committing either technology to competitive play. The NBA has not announced a timeline for moving either experiment to regular-season games.
