NFL players can officially opt-out of this upcoming season for coronavirus concerns.

The NFL Players Association sent out a memo to players and agents on Sunday outlining the specifics.

Players who decide they don’t want to take part in the 2020 season have until August 3 to do so.

Reportedly, players will get a stipend from owners if they don’t play; $350,000 for medical opt-outs and $150,000 for voluntary opt-outs instead of their normal salaries.

Kansas City Chiefs offensive lineman Laurent Duvernay-Tardif was the first player to announce he won’t play this season. He’s using his medical degree to continue working at a long-term care facility in Canada, helping fight COVID-19.

Training camps for most teams are scheduled to start this week.

The NFL had already announced they are canceling all preseason games.
