Guardian Caps are protective headgear introduced in the NFL to reduce head injuries, particularly concussions. Players are required to wear them during training camp and have the option to wear them during games. The caps absorb a significant amount of impact force, contributing to a reported reduction in concussions among players who wear them. The technology has evolved since its inception in 2011, with the latest version designed specifically for NFL use.

Tennessee Titans tight end Josh Whyle will be one of the first players to wear the Guardian Cap during a regular-season game, following two concussions in less than a year. Whyle aims to prioritize his health and safety on the field, opting for additional protection with the Guardian Cap and a new helmet. The Guardian Cap is designed to reduce the impact of collisions and help prevent concussions, a growing concern in the NFL.
