Bundesliga stars have been warned that catching coronavirus could cause 'irreversible' and 'career-ending' lung damage by a top sports doctor ahead of the league's return this weekend.
The German Football League (DFL) has drawn up strict rules to protect players from the risk of being infected with the virus with games being played behind closed doors and only a limited number of media and officials allowed to attend.
Players have also been told to avoid pre-match handshakes and celebrating goals together ahead of this weekend's return.
The DFL says while no plan could ever be '100 per cent safe', the guidelines aim to create a playing environment with a low, 'medically-justifiable risk'.
However, professor Wilhelm Bloch, from the German Sports University in Cologne, warns that contracting the coronavirus has the potential to end a player's career.
