The NFL's new pass interference review rule will officially be implemented during the 2019 season.
Approved in March, the new rule proposal allows for offensive and defensive pass interference calls and non-calls to be subject to review. Coaches can now challenge the penalties in the first 28 minutes of each half, with the final two minutes subject to booth review, according to Rule 15, Section 3, Article 10 of the NFL Football Operations rule book.
The replay official will only stop the game when there is "clear and obvious visual evidence" that a pass interference penalty may or may not have occurred.
