Below is the verbatim memo sent out by Roger Goodell to all 32 NFL teams on Thursday:
TO NFL PLAYERS AND COACHES:
One of our highest priorities is player safety. We all know that football is a tough game that includes hard contact. But that carries with it an obligation to do all that we can to protect all players from unnecessary injury caused by dangerous techniques from those who play outside the rules.
The video shown today shows what kind of hits are against the rules, but also makes clear that you can play a hard, physical game within the rules.
Violations of the playing rules that unreasonably put the safety of another player in jeopardy have no place in the game, and that is especially true in the case of hits to the head and neck. Accordingly, from this point forward, you should be clear on the following points:
1. Players are expected to play within the rules. Those who do not will face increased discipline, including suspensions, starting with the first offense.
2. Coaches are expected to teach playing within the rules. Failure to do so will subject both the coach and the employing club to discipline.
3. Game officials have been directed to emphasize protecting players from illegal and dangerous hits, and particularly from hits to the head and neck. In appropriate cases, they have the authority to eject players from a game.
