Blatter’s spokesman, Thomas Renggli, tells The Associated Press that he is at “home and fine” after a surgical procedure on his left ear.
The 80-year-old Blatter spent one night at a clinic before being discharged on Thursday, Renggli says.
Blatter spent several days in a hospital in Zurich last November after a stress-related collapse while he was suspended from duty by the FIFA ethics committee and subjected to criminal proceedings by federal prosecutors in Switzerland.
Now barred for six years for conflict of interest, Blatter has an appeal hearing on Aug. 25 at the Court of Arbitration for Sport.
Blatter’s 18-year stint as FIFA president ended in February when former UEFA official Gianni Infantino was elected.
