It was just announced that the NFL has mandated the use of Guardian Caps in the early part of 2022 training camp.
After lab testing showed a “statistically significant” improvement over bare helmets alone, the NFL permitted Guardian Caps in the 2021 season.
Now, after a year of data collection from teams using Guardian Caps, NFL owners announced that the League would mandate the use of Guardian Caps during the early part of 2022 training camp for all OL, DL, TEs, and LBs.
Players will wear Guardian Caps for every preseason practice between the start of the training camp contact period and the second preseason game.
