The statue has been built to recognise the love for the sport in the city.
The Gloucester Gargoyle, known as 'Glaaaawster' in homage to the chant by local rugby supporters, is a rugby player tightly holding a ball while kneeling on the ground.
Very Rev Stephen Lake, Dean of Gloucester said: "Since 1891, Gloucester Rugby Club has played its home matches at Kingsholm Stadium. The matches attract large numbers of loyal followers filling the city with enthusiastic fans, and with the other 'hallowed ground' just a stone's throw away from the Cathedral, it seemed only fitting that 'Glaaaawster' should pay tribute to this much-loved sport."
The clay model has been sculpted by the Cathedral's master mason and over the next six months will be carved into stone.
It's the first of six being introduced to replace those which have worn away on the building.
Each gargoyle represents a different region of the County, Gloucester, Cheltenham, Tewkesbury, Stroud, Cotswolds and the Forest of Dean by reflecting local traditions and heritage.
Their installation will form part of a £530,000 restoration project.
