The vote on adopting the new overtime rule was 30-2.
Other rules changes: a team will lose a down for illegally kicking a loose ball; too many men on the field becomes a dead ball foul; and a player receiving a crackback block is now considered a defenseless player and the hit will result in a 15-yard penalty.
Not passed were proposals to have the booth official handle video reviews rather than the referee, and outlawing the horse-collar tackle made on quarterbacks in the pocket.
Given the NFL's concern with player safety, the failure to extend the horse-collar rule seemed surprising. But competition committee chairman Rich McKay said the ownership "didn't think this can impact on player safety."
"The rule was developed for the open-field tackle when a defender has the chance to do something else (in making the tackle)," he said. "He's also able to use the runner's momentum against him. We didn't think that applied to the pocket, didn't see the injury risk."
Several bylaw changes were tabled until the league meetings in May, including expanding preseason rosters to 90, designating one player suffering a major injury before Week 2 of the season as eligible to return from injured reserve, and moving the trading deadline back two weeks to after Week 8.
McKay expects them to pass at the next meetings in Atlanta.
"There were good ideas and suggestions, no resistance," he said. "We'll work on the language."
