Former Portugal great Eusebio is in a stable condition after having a coronarography performed on him to examine the state of his heart.
Eusebio, who turned 70 in January, travelled with the Portuguese team to Poland and was in the stands for the Euro 2012 quarter-final win over the Czech Republic, cheering alongside former Portugal captain Luis Figo.
He was taken to a hospital in the Polish city Poznan where the coronarography x-ray was conducted.
Eusebio's doctors say he suffers from a high blood pressure and needs regular checks on his heart.
He has been admitted to hospitals three times since December last year.
