The RFU would have to approve any ground we propose to use. I have little doubt that we proposed a ground, on the basis of a Heads of Agreement (most likely with Solihull Moors), and that was why the RFU gave initial consent. They would NOT consent to us changing that to Worcester (out of area and it is WW's ground).
The RFU are under enough criticism as it is, without approving such an idea. Even they are not that stupid.
