Atletico Madrid defender Filipe Luis looks set to be out of action for around three weeks after the club confirmed he has suffered a hamstring strain.
The Brazilian left-back was forced off an hour into Atletico's dramatic 3-2 win at Real Valladolid on Saturday.
And the club announced on Monday following an MRI scan that the 33-year-old sustained a grade one strain.
Although Atletico have not set a specific return date, a rest period of three weeks is usually recommended after such injuries.
As such, Luis will most likely miss Saturday's visit of Espanyol and the trip to second-placed Sevilla on January 6, although he could be in contention to return against Girona in the Copa del Rey three days later.
