Spanish legend undergoes more surgery to relieve pressure
Seve Ballesteros is undergoing a third operation at Madrid's La Paz hospital, following further complications after surgery to remove a brain tumour
The operation will aim to relive the pressure caused by swelling and bleeding.
Ballesteros was taken into the operating theatre in the early hours of Friday morning, with the surgery expected to go on late into the evening.
The 51-year-old was first admitted to hospital on October 6 after being diagnosed with a cancerous brain tumour.
The hospital have described the tumour as an "oligoastrocytoma", with it affecting the cells that cover and protect the nerve cells in the brain and spinal cord.
