Athletic Club’s captain, Inaki Williams, is battling an adductor muscle injury sustained during the recent Champions League clash against Qarabag.
Medical tests confirmed the injury to his right leg’s adductor muscle, but the club has yet to specify its severity.
The setback came suddenly, forcing the Ghanaian striker to request a substitution just before halftime.
Recovery could take anywhere from ten days to eight weeks, depending on how Williams responds to treatment.
This puts his participation against Getafe out of reach and makes his presence in the highly anticipated Basque derby versus Real Sociedad doubtful.
