The King Cross Park RLFC Under 7's fundraiser on Sunday was the idea of George Mayes, of Ovenden, in tribute to his father, Sam Mayes.
Sam, 31, had Type 1 Diabetes and died suddenly on Christmas Eve last year after battling alcohol addiction.
To mark his first birthday without his father, George - who turned seven on Sunday - came up with the idea of a fun day at his team's ground off Hopwood Lane.
The event included a host of stalls and games, as well as a game against Dudley Hill - the team Sam used to play for.
It raised more than £2,500, which will go to charities Andy's Man Club and Taking Action on Addiction.
