NFL players have major questions about how COVID-19 will influence their 2020 campaign. Some have big "what-if" queries in mind.

According to NFL Network's Tom Pelissero, during Friday's NFLPA conference call, Indianapolis Colts quarterback Philip Rivers raised a poignant question: If a player tests positive for COVID during Super Bowl week but is asymptomatic, would he still be required to sit out?

The answer: Yes. However, according to protocols issued by the NFL to teams on Friday, five days need to pass after an initial test, in addition to two consecutive negative tests separated by 24 hours, for an asymptomatic individual to return to play.

The question itself underscores the uncertainty with which players and clubs are entering the 2020 season. Few answers are cut-and-dry at this stage. The answer highlights the precarious nature of the season. It's possible that a player could get to the biggest game of his career in February and be forced to sit at home and watch under quarantine.

The NFL distributed COVID-19 protocols for the 2020 training camp and preseason to teams on Friday.

NFL Network Insider Ian Rapoport obtained the full document, which includes protocols for education, facility management, team travel, media restrictions and treatment and response; enforcement of protocols; and a COVID-19 screening form.
