Former Newcastle United goalkeeper Pavel Srnicek has died at the age of 47, nine days after suffering cardiac arrest in his native Czech Republic.
A big favourite with fans during his first spell at St James' Park between 1991 and 1998, Srnicek collapsed while jogging on 20 December.
He was taken to a hospital in Ostrava and placed in an induced coma.
Srnicek, who also played for Sheffield Wednesday, Portsmouth and West Ham, made 49 appearances for his country.
His agent, Steve Wraith, said brain scans had shown "irreversible damage" and the decision "had to be taken" to switch off his life support machine.
Wraith added: "Pav passed away on the afternoon of Tuesday, 29 December 2015, with his family by his side."
The son of a woodcutter, Srnicek joined Newcastle in 1991 and played under Jim Smith, Ossie Ardiles, Kevin Keegan and Kenny Dalglish.
While Keegan was in charge, Srnicek helped the Magpies win promotion to the Premier League and was an integral part of the squad that came close to winning the title in 1996.
The Magpies led by 12 points in January but tailed off badly to finish four points adrift of champions Manchester United.
Wraith said that his "final conversation" with Srnicek was about getting the 1995-96 team back together for a charity event next year.
He added: "We will make that happen and celebrate this great man's life together. United. Fans and players alike."
Srnicek returned to the club on a season-long deal in September 2006 as cover for the injured Shay Given but was released in May 2007 after making 190 appearances for Newcastle across his two spells.
Before his death, Srnicek was the goalkeeping coach at Sparta Prague and was on Tyneside recently to promote his autobiography.
Following his collapse, Newcastle supporters chanted his name during their Premier League match against Everton on Boxing Day.
In a statement, Newcastle United said: "The thoughts of everyone at Newcastle United are with Pavel's family, many friends, former colleagues and supporters at this very difficult time."
Former central defender Steve Howey, who played with Srnicek at Newcastle, said it was a "devastating day".
He told BBC Radio 5 live: "There aren't enough words to describe such a wonderful, strong, lovely man.
"He was such a big, strong character and fantastic personality and I feel blessed that I was able to be a good friend. We've lost an amazing person, one of our own, and he'll be sorely missed."
