Chelsea midfielder Mateo Kovacic has tested positive for coronavirus just a day after returning to training, manager Thomas Tuchel announced on Tuesday.
The 27-year-old has been out of action since late October and Tuchel had hoped to ease him back into action this week.
N’Golo Kante remains sidelined with a knee issue, while Jorginho has been forced to play through the pain of a back problem and will now miss Wednesday’s Champions League trip to Zenit Saint Petersburg, leaving Tuchel short of defensive midfielders.
“We have bad news because Mateo was in training yesterday and with a big smile and it was a pure pleasure to have him back,” said Tuchel.
