West Ham United forward Dylan Tombides has passed away at the age of 20 following a three-year battle against testicular cancer, the club announced.
A club statement said: "Dylan passed away on Friday morning with his family by his side having courageously fought the disease for three years after initially being diagnosed with testicular cancer in summer 2011.
"He remained a regular visitor to Chadwell Heath throughout his treatment and his positive attitude and professional approach to his football and training always impressed and boosted his team-mates and coaches alike.
"Dylan's amazing resilience and positivity saw him through months of surgery and chemotherapy, while his outstanding talent saw him make his first-team debut in a League Cup tie with Wigan Athletic at the Boleyn Ground in September 2012."
Sad news indeed.
Irons team-mate George Moncur took to Twitter to express his devastation at the news:
