The NFLPA's medical director recommends players wear modified facemasks to protect themselves amid the coronavirus pandemic.

Speaking on Monday's The Adam Schefter Podcast, Thom Mayer said the new facemasks would include some form of either surgical or N95 material.

NFL engineers are testing prototypes with the sports equipment company Oakley, Inc., and Mayer said players could be wearing protective facemasks in the upcoming season.

"Yes, it's a possibility," Mayer said. "Back in early March, I suggested ways to handle the helmets and the facemasks ... the league's bioengineers are testing prototypes with Oakley. They're looking at every issue, including when masks fog up."
