Matthew Rickis, from Armadale, was described by one club coach as a "gifted and talented midfield player" and a "lovely young man."
The talented young Hibs fan, known as Matty, played for Broxburn Athletic Colts Football Club at under-19s level.
A statement on the club's website said: "Everyone at the club is devastated to hear the news late Saturday night of the passing of U19 player Matthew Rickis.
"Matthew had a positive impact on and off the football field. Matthew was a much-loved person and we will all miss him dearly. Our thoughts are with Matthew’s family and friends.

The statement added that opening up and talking about mental health is one of the hardest things to do and that the club wants to actively encourage anyone who wants to talk or who is concerned about themselves or others to not suffer in silence.
Matthew was accepted to start a prestigious football scholarship in the US in August.
Football talent scout agency, Five Star Football, Events made the announcement on social media last summer.
A statement on the Bellshill-based organisation's Facebook page in June 2019 said they were “delighted” to have Matthew in team USA and looked forward to seeing him develop and progress.
On the Broxburn Athletic Colts Facebook page, one coach described Matthew as a "gifted and skillful" midfield player and, aside from his talents, a "lovely young man and a pleasure to coach and know."
