Spanish golfer Seve Ballesteros remains in a stable condition in the intensive care unit of a Madrid hospital four days after he underwent surgery to relieve pressure on his brain.
The 51-year-old, who won 87 titles before knee and back problems forced him to retire last year, underwent surgery early last week to remove a brain tumour after collapsing at Madrid airport.
Ballesteros won the British Open in 1979, 1984 and 1988 and became the first European to win the Augusta Masters in 1980, a title he repeated in 1983.
He was an influential figure in the Ryder Cup, winning 20 points from 37 matches and captaining Europe to victory at Valderrama in 1997.
Known for his flamboyant and imaginative style of play, he won one of his three British Open titles by playing a shot from a temporary parking lot.
