The tumour in golf legend Seve Ballesteros's brain has been removed by doctors after an eight hour operation.
The three-times British Open winner is conscious and in a "stable condition" at a Madrid hospital, The Sun quoted doctors there, as saying.
Ballesteros will remain there until next week to see if the tumour is malignant.
A statement released by La Paz Hospital said: "The operation concluded without complications. He is currently conscious, although he will not be able to receive visits over the next few days until he has recovered from surgery."
Ballesteros was admitted to hospital last week after collapsing at an airport. Doctors revealed he had suffered an epileptic attack caused by the tumour.
