The Shropshire Playing Fields Association has spoken out against plans to sell off a school field for residential development.
Telford & Wrekin Council wants to sell off land at Ercall Wood School to help towards the cost of a new school.
Sport England has also objected to the plans.
Dave Kilby, secretary of the Shropshire Playing Fields Association, said the plans would leave the new school with two football pitches, not enough for the 900 pupils.
Mr Kilby said that the association was also objecting because it didn’t believe an assessment of the need for open space, sports and recreation facilities has been carried out.
“Shropshire Playing Fields Association has offered to carry out this assessment with the support of the school PE teachers to ensure the right quantity and quality of facilities will be provided, but to date this offer has been ignored,” he said.
“Given that the school has a long record of taking part in rugby activity, where will the school now play their competitive fixtures?”
A spokesman for SportEngland, which has been consulted by Telford & Wrekin Council on the plans, said the overall playing field area will be less at the new school than was available at the old school.
“Sport England is objecting on the basis that the replacement playing field area is not equivalent or better,” he said.
“The proposed area of playing field is not equivalent to the existing fields in quantity or functionality.”
