The World Snooker Tour described Griffiths as an all-time snooker great in their condolences to Terry’s family and many friends, saying he was loved and respected by everyone in the sport.
The Welshman was a fixture at the top of the sport during the 1980s and early 1990s, reaching at least the quarter-finals of the World Championship for nine straight years — including the final again in 1988.
He retired from playing after a first-round defeat by Mark Williams at the 1997 World Championship.
Griffiths coached a number of top players including Williams, Stephen Hendry and Mark Allen.
