I don't participate in any of the sports teams so I can't say how things are really going there. However, all athletes are usually quite rich people who can afford not to work for a long time, especially if they have grounds in the form of the fact that during the game they are at risk of contracting coronavirus.
There is no doubt that athletes are rich because they got the money from sports and the sponsor. That people make a contract with the sponsor by promoting their product to the public, which makes them get paid. If they don't work or there are no events as in the pandemic, they still have money in their bank account, and that is more than enough to lives. I think it is no problem to confirm that they don't want to risk their lives from the Covid-19, and I think their club will allow them not to participate in the events.
The more money a person has, the more they can afford. Especially when it comes to his health. Therefore, athletes here are in a better position than most sports fans who need to go to work to continue paying bills.
