As is the case almost every offseason, the NBA Board of Governors has approved of a new rule change, this one involving use of referee-initialed instant replay in the final two minutes and overtime. Per NBA.com:
The NBA Board of Governors today approved changes to the league’s instant replay rules on a one-year trial basis for the 2021-22 season.
In an effort to improve game flow, particularly at the end of games, the NBA has eliminated referee-initiated replay review of out-of-bounds violations during the last two minutes of the fourth period and the last two minutes of any overtime period.
