PHOENIX — The N.F.L., in a first, will allow challenges on pass interference 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 about 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.

For one year only, coaches will be able to ask for a video review of possible pass interference plays, whether they have been called on the field or not. Those reviews can come in the first 28 minutes of each half. In the last two minutes of the halves, only replay officials may request a review.
