Piero Hincapie of Bayer Leverkusen tested positive for Corona in his native Ecuador.
The 19-year-old defender immediately went into quarantine. A return to Germany can only take place after a negative PCR test and in coordination with the health authorities.
Depending on how the infection progresses, he will probably be absent for the already short preparation for the second half of the season, which means that coach Gerardo Seoane is already missing his third central defender. Both Odilon Kossounou (Ivory Coast) and Edmond Tapsoba (Burkina Faso) will be away at the Africa Cup in Cameroon until late in January.
