The NFL is testing new protective facemasks with surgical or N95 material, according to the NFLPA's medical director Thom Mayer.

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."
