The 25-year-old has recovered from concussion he suffered in the Celtic League game against Munster last month and is the only addition for the autumn Test preparations at Murrayfield.

Murray said: Im going to take my opportunities as they come and just see what happens but whatever happens, I try my best to just take things in my stride.

Im slightly surprised to be included as I havent had that much game-time, but Im there to train and thats exactly what Ill do.

And Hadden has urged Murray to prove his worth to the squad after his recall.

He said: Im absolutely delighted that Euan has recovered.

He has been showing a lot of potential for a long while now and its time for him to realise that potential.
