The NFL is shipping the Oakley Mouth Shield to all 32 teams over the next week.

The product was designed by doctors and engineers from the NFL and NFL Players Association to try to mitigate the spread of COVID-19.

"That's certainly what we're going to encourage," said Dr. Allen Sills, the NFL's chief medical officer. "And we hope that we're going to land on a product design that's something that everyone would want to wear, because they'll see the value and want that additional protection without any detriment to performance."

Plastic sheets extend down and attach to the face guard. There are airways and openings on the mouth shield but none that allow the direct transmission of droplets, according to the chair of the NFL's engineering committee, Dr. Jeff Crandall


"We've only had it on a few players -- we have 2,500 players in the league -- but I was surprised that ... claustrophobia has not been an issue yet," he said. "I think it will be when we [have more players testing them]."
