The NBA opened an investigation into New York Knicks star Jalen Brunson's heated exchange with courtside fans during Game 1 of the NBA Finals on Wednesday. The incident occurred with 29.4 seconds left while teammate OG Anunoby shot free throws, and Brunson was seen discussing the matter with official Scott Foster afterward.

Brunson finished with 30 points, including 13 in the fourth quarter without committing a turnover, as the Knicks overcame a 14-point third-quarter deficit to win 105-95. The victory extended New York's playoff winning streak to 12 games, with 11 of those wins coming by double figures.

The league also banned two fans for life after a separate incident involving Victor Wembanyama, when one person ran onto the court attempting to take a selfie. This comes amid the NBA's ongoing emphasis on fan conduct, with the league issuing memos this season requiring consistent enforcement of the Fan Code of Conduct at all arenas.

New York's incredible +272 point differential over their 12-game playoff run stands as the best in NBA history across all regular-season and playoff games. The investigation's outcome could impact how the league handles player-fan interactions moving forward in what has become a contentious Finals series.
