Over 20 teams from across the east of England will be at the Gardens to battle it out in the last minis and juniors tournament of the season. The tournament gets underway at 1pm, with the final due to take place at around 3:30pm.
The winners and runners-up will then receive their trophies and medals on the main pitch during the half-time interval of the Aviva Premiership Rugby match between the Saints and London Wasps.
Joules of Olney have become the first company to back a Saints-specific club tournament, following in the footsteps of Land Rover, who sponsor the Under-11 and Under-12 tournaments.
Joules of Olney is the home of traditional British clothing reinvented with a modern twist. As hardwearing as it is stylish, Joules' designs are perfect for men, women and children alike.
