You may have noticed some of the football players’ helmets in Warren County are a bit bigger than usual. Not only are additions being made to help prevent concussions by some local players, MTSU football players are sporting a new look this season with the addition of the Guardian Caps, a 7-ounce, soft-shell helmet cover that reduces the impact of hits by up to 33 percent. According to information distributed by MTSU, while no product can prevent a concussion, MTSU players are wearing the caps in practice for additional padding and to decrease the impacts from head-to-head collisions.
