NFL commissioner Roger Goodell clarified the league's position on the length of players' hair when he met Tuesday in Washington with the NFL Players Advisory Committee.
Goodell told the committee that the league's teams are not asking players to cut their long hair, but would ask players to tuck their hair back into their helmets during games, according to player sources.
However, the issue of safety is a sticking point, too. It pertains to potential concussions because a massive amount of hair tucked into the helmet could compromise the integrity of the helmet's protective measures. Goodell told the advisory committee the league will consult with Riddell, the NFL's helmet provider. It was determined that 62 players with considerable hair length would be affected by a rule change and the committee was not ready to embrace the proposal.

The NFL has complained about hair for as long as I can remember. This is a non issue. The NFL is still around and growing. Long hair is not hurting them one bit
