Here's everything to know about who wears a guardian cap in the NFL, including the players who have worn the new, protective helmet in 2024 so far.

Given Tagovailoa's extensive history with concussions, including this latest head injury that landed him on injured reserve, there was external speculation that he could decide to wear it upon his return. However, that's not the case. Neither the Dolphins nor the NFL can mandate that Tagovailoa wear the Guardian Cap, either.

De’Von Achane became the first Dolphins player to wear a Guardian Cap. Tua Tagovailoa made it clear he won’t be the second.
