In the wake of criticism over a two-game suspension for Baltimore Ravens running back Ray Rice , the NFL has established a six-game unpaid ban for personnel who violate the league 's policy on domestic violence , Commissioner Roger Goodell said Thursday . A second incident would be punished by a lifetime ban from the league , Goodell said in a letter and memo to the owners of the league 's 32 teams . Without referring to Rice by name , he acknowledged in his letter that he made the wrong decision in that case . `` I did n't get it right . Simply put , we have to do better . And we will , '' he wrote . The policy , which is effective immediately , also applies to other types of violence . `` Violations of the Personal Conduct Policy regarding assault , battery , domestic violence or sexual assault that involve physical force will be subject to a suspension without pay of six games for a first offense , with consideration given to mitigating factors , as well as a longer suspension when circumstances warrant . '' Goodell said the circumstances that would warrant a longer suspension include incidents that predate a person 's time with an NFL team or acts that involve choking , repeated blows or a weapon . They also include violence against a pregnant woman or in view of child . Lifetime bans may be appealed after a year . The players union issued a response . `` We were informed today of the NFL 's decision to increase penalties on domestic violence offenders under the Personal Conduct Policy for all NFL employees . As we do in all disciplinary matters , if we believe that players ' due process rights are infringed upon during the course of discipline , we will assert and defend our members ' rights , '' the NFL Players Association said in its statement . Read the letter and memo . Rice was suspended for two games after video showed him dragging his unconscious fiancee -- whom he later married -- from an elevator . Rice resolved the charges stemming from the incident with his now-wife , Janay , and entered a pretrial intervention program in May , the NFL said . Under the program , he wo n't be prosecuted , and the charges will be expunged after a year , the league said . The punishments , both from the NFL and from the criminal justice system , were widely decried as too light , and the issue quickly spiraled into debates over domestic violence and victim-blaming . Opinion : NFL , apologize to women for Ray Rice . Goodell 's letter tells teams to distribute a memo about the new policy to each player and all members of the organizations . The NFL 's Personal Conduct Policy states that employees are `` held to a higher standard '' of conduct . `` Persons who fail to live up to this standard of conduct are guilty of conduct detrimental and subject to discipline , even where the conduct itself does not result in conviction of a crime , '' the policy states . The NFL regular season is 16 games . Ravens ' Ray Rice : 'My actions were inexcusable '
Players union says it will continue to defend players rights . The new policy takes effect immediately , NFL Commissioner Roger Goodell says . The commissioner admitted he should have punished Ray Rice more severely . Rice got two-game suspension after video showed him dragging his now-wife .
