Neck guards will be mandatory at Olympics after Adam Johnson’s death

• IHF order would not apply to NHL and professional leagues
• Move follows Johnson's death during game in October

The International Ice Hockey Federation announced Monday that it is making neck guards mandatory for all levels of competition in the tournaments it runs, including the Olympics and men's and women's world championships.

The mandate would not apply to professional leagues, including the NHL, which currently does not have any cut-proof safety requirements for players. Any sort of mandate in the NHL would require an agreement between the league and players' union, which have been discussing skate blade safety for years.
