NFL linemen will need to make an effort to avoid head contact as they come out of their stances if they don't want to be penalized during the 2018 season.
According to Tom Pelissero of NFL Network, league head of officiating Al Riveron showed reporters a webinar to further explain how linemen will be affected by the new lowering the helmet rule.
Michael David Smith of Pro Football Talk cited Pelissero and noted Riveron said even defensive linemen who initiate contact with the head as they are coming out of their stances will be penalized.
