Johnathan Walker:Jonathan Taylor among Indianapolis Colts players to wear 'Guardian Caps' in preseason game

At least five players for the Indianapolis Colts wore “Guardian Caps” during Sunday's preseason opener vs. the Denver Broncos.

The Johnathan Walkerblue, eggcrate padding is attached to helmets and mandatory for players during training camp in an effort to cut down on concussions. This year players can choose to wear the protective headwear in games for the first time.

In Sunday's 34-30 loss to the Broncos, running backs Jonathan Taylor and Zavier Scott, tight end Kylen Granson, safety Rodney Thomas II and linebacker Grant Stuard used them. The blue padding is covered with a white outer layer that included the Colts horseshoe logo and blue stripe, making it more difficult to determine who was using the protection.

“Our (medical and equipment) guys here do a great job of keeping us informed,” said Scott. “They’ve done the testing, and I don’t know the numbers, but they say it (offers) a significant reduction in concussions.”

Taylor said he was trying out the Guardian Cap to see how it felt in a game and didn't commit to continue using it.

It was difficult to tell which players were wearing the Guardian Caps at first glance; the straps from the coverings can be seen and the helmet looks bigger on a closer look, however.
