In March 2010, the NFL amended its rules for postseason overtime after a vote by the team owners, with the rule being extended into the regular season in March 2012. If the team that receives the kickoff scores a touchdown; or if the defence scores a safety on its first possession, it is declared the winner. If it scores a field goal on its first possession, however, it then kicks off to the opposing team with an opportunity to score; if the score is tied again after that possession, true sudden death rules apply and the next team to score by any method is declared the winner.
