Giannis Antetokounmpo beat the Thunder just before the buzzer on Friday.
But before his game-wining bucket, the Buck star was out of bounds.
The Thunder saw it in the moment, but the officials missed the call. The NBA confirmed that on Saturday in its daily Last 2 Minute report, which reviews the final two minutes of games that are within three points at any point during that period.
The league deemed officials made an incorrect no call on Antetokounmpo for stepping out of bounds when he drove past Josh Huestis and scored over Russell Westbrook.
