German side RB Leipzig have revealed that six more players and staff have tested positive for Covid.
Head coach Jesse Marsch and goalkeeper Peter Gulacsi were already in quarantine after testing positive last week.
And Leipzig reported six more positive coronavirus cases on Friday following their Champions League game against Belgian side Club Bruges in Manchester City's Group A.
Defender Willi Orban, forwards Yussuf Poulsen and Hugo Novoa, and goalkeeping coach Frederik Gößling all tested positive for COVID-19 after returning from Belgium, while defender Mohamed Simakan and a member of the backroom staff were infected despite not traveling, Leipzig said.
Poulsen reportedly gave an emotional team-talk before Wednesday's 5-0 win in Belgium.
Marsch and the players will miss Sunday's home Bundesliga game against Bayer Leverkusen.
The game was already scheduled to be played behind closed doors due to high numbers of the virus in Saxony.
'As usual, we are in close exchange with the health authorities and will continue to test closely on an ongoing basis,' the club said in a statement.
Leipzig's Champions League game against Manchester City on December 7 will also be played behind closed doors.
The club carried out tests on 61 staff members on Thursday. It said it remains in regular contact with the local health authority and will continue to carry out tests on a regular basis.
Leipzig previously said all of its players and staff members were either fully vaccinated or have recently recovered from Covid-19.
