Atletico Madrid confirmed Antoine Griezmann has been granted permission from health authorities to return to training.
Griezmann was among five to test positive for COVID-19 on December 30 along with coach Diego Simeone, Koke, Hector Herrera and Joao Felix.
All of them went into immediate isolation, with only Simeone being able to leave quarantine in time for Sunday's 2-0 LaLiga win over Rayo Vallecano.
But Griezmann has been cleared to return to the training pitch as well after his latest test came back negative, making his a case of "resolved infection".
An Atletico statement read: "Antoine Griezmann has received clearance from LaLiga to return to training.
"The French player represents a case of resolved infection that meets the conditions set by the Strategy for Early Detection, Surveillance and Control of COVID-19 of the Ministry of Health, dated December 19, 2021."
As such, Griezmann could potentially feature against Rayo Majadahonda in the Copa del Rey on Thursday.
Otherwise, he will hope to be involved away to Villarreal on Sunday.
