BILBAO, Spain (AP) - Athletic Bilbao says defender Yeray Alvarez will undergo chemotherapy after tests revealed an anomaly in a testicle that had previously been treated for a tumor.
The Spanish club says it expects him to be out for three months.
The 22-year-old Alavarez was treated in December for a tumor found in his testicles. He returned to play for Bilbao before the end of the season.
He had been called up to play for Spain’s under-21 team.
