The tournament has been organised in aid of Cotswold Kitty Walks the Way, with eight teams from across Gloucestershire involved.
Eight-year-old Kitty, who attends St Gregory’s school in Cheltenham, suffers from Cerebral Palsy and an operation is available, although it is not funded by the NHS.
The operation will take away spasticity and help Kitty with her wish to walk.
Kitty's brother Jack Kerr plays for Cheltenham Saracens, and the club have announced the teams for their tournament.
Cheltenham Saracens will host the tournament on Saturday, July 8, with Smiths, Old Pats, Cheltenham, Cheltenham North, Chosen Hill, Bredon and Tigers Old Boys involved as well as Sarries themselves.
