Félix, the forward who has become a key player for Atlético Madrid this season, is set to miss at least one month with a knee injury.
The Spanish club announced on Friday that Félix had suffered a setback in his recovery from a knee problem and would be out of action until at least mid-March.
Félix, who joined Atlético from Real Betis last summer, has made a strong start to life in La Liga, scoring six goals in just eight appearances for the club so far this season.
His injury comes as a blow for Atlético, who have already lost star striker Diego Costa to injury and are currently struggling to keep up with Barcelona in the league standings.
However, they will hope that their squad depth and experience will allow them to cope without Félix for a period of time.
Injuries can be a major concern for any team, but Atlético's recent form suggests that they are well-equipped to deal with the absence of such a key player.
With Félix out, Atlético will need to find a way to replace his contributions on the pitch, while also ensuring that their other forwards continue to perform at a high level.
Despite the setback, there is no doubt that Atlético will be looking to bounce back and secure a place in the top four of La Liga come the end of the season.
