Premier League players could refuse to return to training on Monday even if Project Restart gets the green light.
Clubs fear players with asthma, family members with underlying health issues and BAME players will not sign consent forms to return to training.
Mirror Sport has been told one club has already been informed by two players that they will not report back because they have major concerns.
Aston Villa boss Dean Smith has already gone public to say two of his players have asthma and may not play while a Brighton first team squad member has a partner with a serious health issue.
Raheem Sterling and Danny Rose have also voiced concerns ahead of crunch talks between players, the Premier League, Professional Footballers’ Association and medical experts on Wednesday.
PFA representatives and club captains will take part in the discussions and report back to their dressing rooms but the outcome will be crucial in trying to get football restarted with the Premier League hoping that the first phase of non-contact training can begin next Monday.
Players are being sent a 40 page document with new training protocols and have also been given a PFA update to give them expert advice on asthma and the increased risk for BAME players.
It will also include guidelines on parking three spaces apart from team mates, wearing face masks in training, not sharing a car to training and also the twice-a-week testing process.
Clubs will also have to appoint a senior member of staff to be their Covid 19 officer but they must not be from their medical staff but will get extra training and advice on protocols.
But the PFA will also want assurances that if players do opt out and refuse to train that it will not be held against them as chief executive Gordon Taylor admitted asthma sufferers and BAME players may have particular concerns.
Taylor said: “There are certain players who are going to be more vulnerable than others according to particular conditions which is another part of the equation.
“I think it’s a time when everybody is entitled to make their own decisions so long as we put in place the very best people to answer any questions or misgivings they have and that’s what we are trying to do.”
