Newly allowed as in-season safety measures this year, the Guardian Caps are presently believed to reduce concussions by 46%, and some Dolphins staffers, including head coach Mike McDaniel, approached Tagovailoa about using the added covering during his recovery, per NFL Media.

Miami Dolphins quarterback Tua Tagovailoa has been out since he suffered a concussion in Week 2. A report Saturday gave an update on Tua's return.

Tagovailoa is a high-profile quarterback who has now sustained three diagnosed concussions over the span of two years, plus another head injury that prompted the NFL to change its concussion policy. So, naturally, Tagovailoa's health and playing future have been among the most heavily scrutinized stories in the NFL this season.
