Edinburgh Rugby are set to play at Myreside for the second half of next season.
The SRU are believed to be in negotations to use the ground – home of Watsonians – from January to May next year with a view to making the move permanent should it be a success. It is understood Myreside’s capacity would reach 6000 with temporary stands.
Last February, the ground hosted a PRO12 clash between Edinburgh and Ospreys while BT Murrayfield was being used for the Six Nations.
An SRU spokesman confirmed: “Edinburgh Rugby and George Watson’s College can confirm discussions are being held and specific details will be announced in due course.”
