Motherwell captain Phil O'Donnell has died after collapsing towards the end of his side's Scottish Premier League game against Dundee United.
The 35-year-old midfielder fell to the ground just as he was about to be replaced with Marc Fitzpatrick near the end of Motherwell's 5-3 victory.
O'Donnell was treated for around five minutes on the field before being taken to a waiting ambulance.
But his death was later confirmed by Well chairman Bill Dickie.
Scottish Football Association chief executive Gordon Smith led the tributes.
"This is absolutely devastating news," he said.
My thoughts are with his family at this tragic time

"Phil was not just a wonderful footballer, he was a great human being.
"My thoughts are with his family at this tragic time."
Motherwell manager Mark McGhee had spoken briefly to the press after the game before going to hospital to find out how the skipper was.
"He's had some sort of collapse," he said at the time.
McGhee said O'Donnell's substitution had been "an absolute coincidence" before his sudden seizure.
"We just felt we would save him a bit for Wednesday," said the manager.
O'Donnell's nephew, David Clarkson, was substituted moments later after scoring two goals in the Scottish Premier League match.
McGhee said: "We took Clarkson off because he got a fright from the nature of the collapse.
"A few of the boys got a fright."
A news conference has been called at Wishaw General Hospital, which will be addressed by chief executive Ian Stillie.
O'Donnell, who earned one cap for Scotland, was lauded as one of the country's brightest talents when he broke into the Motherwell first team as a teenager.
He moved on to Celtic for a club record £1.75m fee, but injury problems were to blight his time with the Glasgow club and his next club, Sheffield Wednesday.
O'Donnell returned to Motherwell in 2004 and became club captain, playing beside his nephew.
