NBA Pilots Sensor-Equipped Basketballs to Separate Objective Data From Official Judgment

The NBA has launched a series of technology trials during the 2026-27 preseason, deploying sensor-equipped basketballs and referee wearables to evaluate their potential for future game officiating. The testing began in select games during the 2026-27 preseason, marking a shift toward the potential automation of objective rulings such as goaltending and out-of-bounds calls.

The primary hardware being tested is a basketball developed by Wilson that contains a Bluetooth sensor. This “smart” ball is designed to collect spatial data in real time, providing the league with precise tracking of the ball’s position relative to the court and the rim. Alongside the new basketballs, game officials are wearing wrist devices that facilitate direct communication with the NBA Replay Center.

New wearables allow officials to receive instant alerts for scoring changes and clock malfunctions.

Separating Objective Data from Subjective Judgment

The league’s strategic goal, according to President of League Operations Byron Spruell, is to separate “objective” measurements from “subjective” judgment calls. By utilizing smart basketballs and official wrist wearables, the NBA aims to eventually automate decisions that involve clear physical boundaries, such as whether a ball hit the out-of-bounds line or if a block occurred while the ball was on a downward trajectory.

The referee wristbands serve three specific functions during the trial period:

Providing alerts for scoring changes and corrections. Notifying officials of game clock malfunctions or timing discrepancies. Streamlining the flow of information during formal replay reviews.

The current 2026 trial features Wilson’s Bluetooth technology. The wearables used by the referees also underwent a successful trial during the 2026 Summer League before being cleared for this preseason’s expanded testing.

Limitations of the 2026 Trial

While the hardware is active during select preseason matchups, the data collected will not be used to influence live game play. The league has confirmed that no calls will be made or overturned based on the sensors during this period, as the technology remains in a research-only phase. This approach allows the league to verify the accuracy of the sensors and ensure the weight and bounce of the Wilson ball remain indistinguishable from standard game balls.

The NBA has further stated that this technology trial will not extend into the 2026-27 regular season. Officials will continue to rely on traditional human observation and existing replay protocols once the regular season tips off, using the data gathered this month to refine the logic for potential implementation in future seasons. By automating binary decisions, the league intends to allow human officials to focus more closely on complex “judgment” calls, such as shooting fouls and off-ball contact, which sensors cannot yet accurately interpret.
