Allen Sills, the NFL's medical director, announced on Friday that since players from all 32 teams began using 'Guardian Caps' (padded coverings over their helmets) last summer, the incidence of concussions has decreased by approximately 50 percent.

"The 'Guardian Caps' have been a resounding success for the NFL. They have achieved a significant reduction in concussions during training by about 50 percent over the last two preseason periods," stated Sills.

Starting from the 2023 preseason, and after extensive research, the NFL mandated that players wear these padded covers during training sessions leading up to the regular season to lessen the intensity of contact that previously resulted in a high number of concussions.

Initially, there were concerns that wearing this gear could lead to overheating during practice or contribute to neck injuries. However, the benefits have proven to be significant, with a marked reduction in concussions allowing players the option to wear 'Guardian Caps' not only during preseason games but also in regular-season matches, as has been the case in 2024.

"We see no negative effects from players wearing 'Guardian Caps' in games, so we find no reason why they shouldn't have the freedom to use them," explained Sills.

In each of the four weeks so far this season, between five and ten players have utilized this equipment each game.

While the NFL hopes to see an increase in the number of players opting to wear 'Guardian Caps', it does not plan to make their use mandatory due to the ongoing improvements in helmet safety technology, which continues to enhance the ability to reduce the force of impacts.
