Dennis Taylor has hailed Steve Davis for his contribution to snooker after the six-times world champion announced his retirement.
The 58-year-old announced his decision live on the BBC yesterday during his work as a pundit at the World Championship at the Crucible in Sheffield.
Taylor, who won the world title in 1985 after an epic battle with Davis, said: "It is a sad day because he changed snooker completely when he came on the scene.
"He was the first player to put in six, seven hours practice. What an ambassador he has been," he added.
Davis, who is also a DJ, played in last week's World Championship qualifiers but was beaten by Dubliner Fergal O'Brien.
The Londoner - who dominated the game in the 1980s, earning over £5.5million in prize money - said: "The Fergal O'Brien match was my last and I told Barry Hearn (Davis' manager) it was time to call it a day.
"My father passed away recently and it was the natural time to stop playing.
"I should have done it ages ago - I played a bit for my father. I am delighted to have had such a great time in the game. I was lucky to have a hobby as my profession.
"It has been a fantastic time. The game will move on but I feel like the grandfather of the sport."
Meanwhile, in yesterday's World Championship action, Anthony McGill - last year's surprise package at the Crucible when he reached the quarter-finals - pulled off another giant-killing act with a 10-8 victory over Shaun Murphy, who won the title in 2005.
McGill, who will face Marco Fu in the last 16, said: "I suppose I could win it. I've got a cue in my hand and I'm still in it. I didn't come here to win, I'm here just to try my best and see where that gets me."
Alan McManus beat fellow Scot Stephen Maguire 10-7, while five-time champion Ronnie O'Sullivan leads David Gilbert 6-3 overnight.
