Barcelona's forward, Antoine Griezmann, has been ruled out for two matches after sustaining a muscle strain in his right thigh during training on Wednesday.
The France international was substituted off the pitch in the first half of their match against Athletic Bilbao, and will now be missing the upcoming games against Osasuna and Real Sociedad.
Griezmann has had a difficult season so far, with the club's struggles under new coach Quique Setien causing him to drop down the pecking order in attack.
His injury means that Barcelona will have to find another forward to fill in for him, potentially turning to loan signings like Raphinha or Ousmane Dembele.
Dembélé, who is currently out injured himself, is set to miss the next two matches as well, adding further pressure to the team's front line.
It remains to be seen how this setback will affect Barcelona's chances of success in the coming weeks, but it does highlight the importance of having depth and flexibility within your squad. With the likes of Gerard Piqué, Sergi Roberto, and Jordi Alba all unavailable, it may mean that Barcelona will need to rely more heavily on their substitutes in the future.
