The 13-year-old son of former United States captain Claudio Reyna has died of cancer.
The sad news was confirmed Thursday on the website of Scottish club Rangers, where Reyna spent two and a half seasons.
"Rangers Football Club tonight learned of the tragic news that Claudio Reyna's son Jack has sadly died after a battle with cancer,'' the statement read.
"The thoughts of everyone at the club are with Claudio and his family at this extremely difficult time.''
Reyna spent two years in Glasgow from 1999, when Jack was born, to 2001.
Gers boss Ally McCoist said: "We have just heard the sad news that Claudio Reyna's son Jack has lost his battle against cancer.
"On behalf of everyone at Rangers I would like to offer my sincere condolences to Claudio and his family at this difficult time.
"Losing a child at just 13 is a tragedy and puts football into perspective.''
''It is with a heavy heart that we confirm that Jack Reyna lost his battle with cancer (Thursday),'' the family said in a statement released through U.S. Soccer. ''Jack was so courageous during his two-year fight that he's become a hero and inspiration to many. Surrounded by his entire family, Jack passed peacefully at the age of 13.''
Reyna also had spells with Sunderland and Manchester City before he returned to his homeland for a season with New York Red Bulls.
Injury forced Reyna to announce his retirement four years ago.
