Guest sides drawn from Scotland and England will be competing for the honour of winning the inaugural 'Glasgow City Sevens'.
Glasgow Warriors Academy will be taking part and will be including some familiar names in their line-up.
Sevens from Sale Sharks and Edinburgh Rugby Academy will also line up alongside "King of the Sevens" Melrose and Scottish Premiership Champions Glasgow Hawks in a Tournament which is now firmly on course to becoming the 'Blue Riband' event of the sevens circuit outside of The Greenyards.
There has been a sevens tournament at Dumbreck each year since 1950, and this year's event marks the culmination of an excellent season for Cartha Queen's Park, including the winning of promotion to Division Two of the Premiership.
The 'Glasgow City Sevens' will be preceded by a Rugby Union Skills Clinic for children from 9 to 14 years. This will run from 9:30am until 12:00 noon, and will involve coaching provided by Glasgow Warriors and Sale Sharks.
