NFL players could wear modified facemasks next season, with league engineers and equipment maker Oakley already testing prototypes, according to NFL Players Association medical director Thom Mayer.
Speaking on ESPN's The Adam Schefter Podcast, Mayer said: "there probably will be a recommendation" for players to use the face coverings to protect from coronavirus when the NFL season begins, now scheduled for September.
"The league's bioengineers are testing prototypes with Oakley," Mayer said.
"They're looking at every issue, including when masks fog up."
