Normally at this time of year the Dallas Cowboys, like every other NFL team, would have 90 players on their roster as they are in the middle of training camp. That is not the case here in 2020.
In order to comply with Covid-19 protocols the NFL has had teams operate with 80 players. As far as roster distinctions are concerned there is a Covid-19/reserve list that is specifically intended for players that either test positive or have been around someone that is known to have tested positive.
The Cowboys have had two players on this particular list, Jon’vea Johnson and Saivion Smith.
