No it won't destroy him. It won't do him any harm at all. No-one expects anything from him so there is no pressure on him. He can only benefiit from the experience.

How old were Horne and Yeaman when they made their first team debuts?

Lancaster deffo playing.

Sa to play 2nd row.

So much for bringing in a new centre...

Drop Rankin, put Azza to half back. Horney on the bench to cover the back line which has questionmarks all over it.

I'm assuming he'll play centre when he's up to speed.
His fitness and skills won't be 100% so better to put him in the 2nd row to begin with while he's getting back up to speed and can be brought off less disruptively. I very much doubt he'll be able to do a full 80 mins atm.
