The potential return of the Bundesliga is under increased scrutiny after Hertha Berlin forward Salomon Kalou posted a Facebook video of himself ignoring social distancing measures.
Former Chelsea player Kalou, 34, was seen shaking hands with his Hertha team-mates and interrupting a medical check-up of another. He has since deleted the video.
The images have been called "unacceptable" by the German Football League (DFL), which has been working towards restarting the football season later this month - subject to government approval.
Hertha Berlin have suspended Kalou with immediate effect, saying the player had shown behaviour that "is neither appropriate to the situation nor corresponds to the rules of conduct of the club".
The Bundesliga club said the incident came after the team returned negative tests for coronavirus, which Kalou reacted to by shaking the hands of his team-mates, contrary to instructions from medical staff.
General manager Michael Preetz added: "With his video, Salomon Kalou has not only done a great deal of damage to Hertha BSC, but also created the impression that individual players are not taking the issue of coronavirus seriously, in a time of great discussion on the resumption of football and the role of the professional game."
Kalou, who has 97 caps for the Ivory Coast, said: "I am sorry if I gave the impression that I am not taking coronavirus seriously. The opposite is the case, because I am especially worried about the people in Africa, because the medical care there is nowhere near as good as in Germany.
"I didn't really think it through, and was excited that my tests came back negative.
"I would also like to apologise to all those who appeared in the video who didn't know that I was broadcasting live and whom I didn't want to bring into this situation."

When are PL clubs returning to training?

Arsenal were the first to welcome back members of their first-team squad, on April 27, with players training individually in accordance with government health guidelines.
First-team players at Wolves will return to the training ground next week for individual sessions and fitness training. Strict social distancing measures will be in place and the players will be required to wash their own kit.
The Professional Footballers' Association (PFA) say there will hold a wide-scale consultation with players to understand their feelings about a return to playing as plans continue to restart football.
The Premier League met on Friday to consider proposals for "project restart" with a number of different measures being considered.
Former Watford striker Marvin Sordell, who was last week appointed to the FA's Inclusion and Advisory board, says players in England should be given the right to refuse to play amid the coronavirus pandemic.
He said: "You have to respect people's opinions in this. Many will say they earn a lot of money so they should just go and play.
"This virus at times is a matter of life and death and any game of football - regardless of the famous saying - football isn't more than life or death.
"I think people's own situations need to be respected. If they want to play, and it's safe to do so, then allow them to play. If they don't want to play because they don't think it's safe to do so, I think that needs to be respected."
