Hull's record goalscorer Chris Chilton has died, the club announced on Thursday.
Chilton, who was 77, scored 222 goals for his hometown club between 1960 and 1971, later returning for a spell as assistant manager.
Hull confirmed Chilton, who had been suffering from Alzheimer's disease and vascular dementia since 2012, died overnight.
Late last year, a fundraising appeal helped raise more than £40,000 to contribute towards his care needs.
A club statement read: "Our thoughts are with the Chilton family, and their many friends, at this sad time.
"His contribution to Hull City will never be forgotten.
"Club flags will fly at half-mast as we remember a man who was simply worshipped by the thousands that watched him play at Boothferry Park, and whose goalscoring exploits may never be bettered."
