THE teenage son of former Black Cats star Claudio Reyna has lost his battle with cancer.
The American midfielder and wife Danielle have been left devastated by the death of 13-year-old Jack.
It is understood the youngster, who was born in Scotland while the 38-year-old played for Glasgow Rangers, had been suffering from a paediatric brain tumour for the past three years.
Today, Sunderland AFC bosses sent their condolences to the Reyna family, who live in Westchester County, New York.
A club spokeswoman said: “Naturally, everyone at Sunderland is desperately saddened to hear this tragic news.
“The thoughts and prayers of everyone at the club are with Claudio and his family at this time.”
Claudio, who also captained his national team, made 28 appearances for the Black Cats from 2001 to 2003, although his time at the club was disrupted by injury.
Martyn McFadden, editor of Sunderland fanzine A Love Supreme, said: “Claudio did well during his spell at Sunderland and was a likeable guy.
“It’s tragic that his son has been taken from him at such a young age.
“Cancer is such a cruel disease and sadly affects too many of us.”
Messages were also posted on the Ready to Go football forum website.
“My deepest condolences go out to the Reyna family,” said one Black Cats supporter.
Another added: “Thoughts and prayers with Claudio Reyna and his family.”
Jack’s death was confirmed on the Rangers’ website and their official Twitter account.
Manager Ally McCoist said: “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.”
A statement from Rangers added: “The thoughts of everyone at the club are with Claudio and his family at this extremely difficult time.
“Claudio spent two years in Glasgow from 1999, when Jack was born, to 2001.”
Manchester City and Olympic Team GB defender Micah Richards, who played alongside Claudio, said: “Hearing the news about Jack is just awful.
“Claudio is such a nice guy and a dedicated family man.
“I just feel terrible for Claudio and his family.
“Jack was such a young lad.”
