Per NFL.com:
NFL owners have voted at the NFL Annual Meeting to change the regular-season overtime rules to match the playoff format and have turnovers automatically reviewed.
Each team will have an opportunity for a possession in overtime unless the team that receives the first kickoff scores a touchdown on its opening drive.
Teams will no longer need to challenge turnovers, as is the case with scoring plays.
Proposals that would have changed the injured reserve designation and pushed back the trade deadline were tabled, but NFL Network insider Jason La Canfora reported that many executives believe both the changes will pass at a later date.
Rich McKay, the co-chair of the competition committee, said some proposals would be revisited in May after their language was tweaked or they were reviewed by the NFL Players Association.
