Thiago Alcantara is self-isolating after he tested positive for the coronavirus.
The Liverpool midfielder missed the last two games against Lincoln City and Arsenal.
He will now remain in self-isolation as the Reds look to follow the protocols for players who contract COVID-19.
The club's first-team doctor, Dr Jim Moxon, said: "It is the choice of each individual whether they reveal publicly the outcome of a COVID-19 test.
"We have followed all the protocols to the letter and Thiago is OK. He will be self-isolating now as per the guidelines and hopefully he'll be back with us soon."
