PHOENIX — The N.F.L. will allow challenges on pass interference plays next season, whether flags were thrown by referees or not.
The rule change, approved by a 31-1 vote of the league’s owners on Tuesday, came two months after a controversial non-call on an apparent pass interference play influenced the outcome of the N.F.C. championship game between the Los Angeles Rams and the New Orleans Saints.
Many Saints fans, believing that the non-call led to their team’s loss, refused to watch the broadcast of the Super Bowl between the Rams and the New England Patriots.
