Félix, the forward for Atlético Madrid, has sustained a knee injury that is likely to keep him out for one month.
The news was confirmed by the Spanish club on Friday morning, with Félix being ruled out of their upcoming matches against Real Betis and Valencia.
The Argentine international has been in good form this season, scoring four goals and assisting three more in just six league appearances.
His absence will be a blow for Atlético, who have struggled without his pace and creativity up front.
However, there is still hope that he can recover in time for the latter part of the season, which could see them compete for honours in the Copa del Rey and La Liga.
In the meantime, Atlético will have to rely on other forwards such as Luis Suárez and Diego Costa to step up and fill the void left by Félix's absence.
It remains to be seen how long it will take for Félix to fully recover from his injury, but in the meantime, fans and supporters of Atlético will be hoping that he returns to full fitness soon.
