Scottish youth football has been hit by a double tragedy in separate incidents.
Jamie Skinner, who was until recently on Hearts books, was playing for Tynecastle FC's Under-14 team at the Saughton astro pitch when he fell to the ground.
Attempts by ambulance staff and others to revive him failed.
Tynecastle FC said Jamie would have had a bright future in the game and everyone at the club was "in total shock" at his death.
Jamie moved to the club recently after playing for Hearts Under-14s.
As a mark of respect all Tynecastle teams will hold a minute's silence before their next game.
St Mirren defender Danny Grainger, who formerly played for Hearts, tweeted: "seen the news about the young lad who played for tynecastle u14's! Terrible news and my thoughts go out to his family at this terrible time."
Meanwhile, Hibernian football club have confirmed the death of an 18-year-old player in their youth team.
David Paul, the club said, passed away in the early hours of Sunday at his home in Edinburgh.
There are understood to be no suspicious circumstances surrounding his death.
Hibs chairman Rod Petrie said: "Everyone at the club is deeply affected by this. David was a talented and promising young footballer, and a fine young man.
"Our thoughts - and the thoughts of the entire Hibernian community - are with his family at this dreadful and difficult time for them.'
