The former Great Britain scrum-half and loose forward died at Pinderfields Hospital in Wakefield last Thursday morning, surrounded by his family.
Mr Fox, who was 73, had a highly successful career with Featherstone Rovers and still holds the club's try-scoring record of 162.


He is also third in their all-time goal kicking list with 503 in 369 appearances.
Mr Fox retired in 1971 after 500 appearances with Rovers and then Wakefield Trinity.
He was one of three rugby-playing brothers from Sharlston, with Neil and Peter Fox, and lived in Featherstone for a number of years before he moved to Walton Manor residential complex in Wakefield.


Peter Fox – a former Rovers coach – led both teams out at The Chris Moyles Stadium on Sunday for the Featherstone and Halifax match as a tribute to his brother.
The stadium also observed a minute's silence in his honour.
Veteran politician and lifelong Rovers' fan Lord Lofthouse said: "Don will always be remembered throughout the rugby league world. I am proud to have known him as a friend and a great rugby league player."


He added: "It is difficult to highlight the many games Don controlled and brought victory, and great pleasure, to Rovers' fans, not least myself."
Featherstone Rover's chairman Paul Coventry said: "As a player and a man, he was an inspiration to us all. His skill as a player will always be remembered and respected as one of the greats of Rugby League."


An inquest this week heard Mr Fox – who had suffered from depression for a number of years – had been admitted to the Chantry Unit of Fieldhead Hospital in Wakefield to review his medication when he had a fall on Wednesday August 20.
The fall was not witnessed and he was taken by ambulance to Pinderfields Hosptial where a scan showed he had suffered head injuries.


He died in the early hours of the following day.
He leaves a wife Mary, son Gregory and granddaughter Lauren.

Donations in lieu of flowers should be made to the Prince of Wales Hospice.
