The sixth Andy Knight Memorial Trophy will be held at Priory Lane on Sunday, August 24.
Kick-off for the veterans football tournament and fun day is at 10am with the final scheduled for 5pm.
12 teams will enter with all proceeds in aid of the Children with Cancer Fund (Polegate).
Attractions on the day will include a tombola, fairground rides, a raffle, soft play, a bouncy castle, face painting and a live band.
The tournament was established in 2009 by Trudi Knight after her husband Andy Knight died with lung cancer aged 44.
Andy was passionate about football, an avid Arsenal fan, and a well-respected local referee.
In six years the tournament has raised more than £10,000 for this charity.
