The MLB and the Players Association continue to discuss only what teams can announce – or not – about players who are on the COVID-19 injured list.
The player does not have to give a positive result in order to get into this newly created list. An assessment by medical personnel or the impact of those with coronavirus may result in COVID listing. It is expected that teams will test staff who will be participating in Spring Training 2.0 on Wednesday and Thursday, and then every two days thereafter.
In negotiations with MLB, the union has historically emphasized players' right to privacy. Thus, it is possible that players who are on the COVID List will simply be declared as being on the Wounded List, and this will depend on the individual players to uncover the reason.
Under the Basic Agreement, clubs are allowed, for public relations purposes, to disclose information about injuries related to employment: 1) the nature of the injury, 2) the prognosis and alleged absence, 3) the type of treatment / operation performed. That's why you traditionally hear something from the team, for example, John Doe suffered a sprain of the 2nd class of the ankle, is expected to miss 4-6 weeks, rehabilitation without surgical intervention is recommended.
For any other medical conditions that prevent the player from providing services, teams can only disclose that the medical condition does not allow the player to play and for how long he may be absent. The new COVID list seems to fall into this category if the Basic Agreement is used as a guide, unless the MLB and the union agree otherwise.
MLB and the union are also continuing to discuss whether there will be a wide public record of the trials and positive results for COVID-19.
