NFL training camps are already in full swing, but there are some notable absences.
Kansas City Chiefs offensive lineman Laurent Duvernay-Tardif became the first NFL player to opt out of the 2020 season last Friday, citing health concerns related to the coronavirus pandemic.
Since then, multiple players have followed suit, continuing a trend across all major North American professional sports of players declining to participate in their seasons as COVID-19 persists in the United States.
