An Eibar player has tested positive for coronavirus antibodies, according to Marca.
The player in question must self-isolate at home for the next few days.
The identity of the player is unknown but Diario Vasco have reported, and MARCA have confirmed, that he tested positive before the second round of coronavirus testing on Friday.
A positive antibody test means that the player has already had COVID-19, has recovered and there is little risk of him infecting others.
This will not be counted as a positive test by LaLiga, who are only recording players who currently have coronavirus in their list.
