I think it's unlikely for any of the recent call-ups to be included in the 23 for Scotland. I'm not even sure that Arnold, Skelton and Latu are available for this match. But, if they are, they are more likely in my opin ion to just be squad members while they learn the ropes under Rennie. Similar, I think, to the way Rennie brought Quade and Kerevi into the team after a few weeks in the squad.
I think we might see:
1. Slipper
2. Fainga'a
3. Tupou
4. Swain
5. Philip
6. Leota
7. Hooper
8. Valetini
9. White
10. JOC (James O'Connor)
11. Petaia
12. Paisami
13. Ikitau
14. Wright
15. Kellaway
though I wouldn't mind 11. Wright, 14. Kellaway, 15. Petaia.
16. McInerney
17. Bell
18. Ala'alatoa
19. Rodda
20. McDermott
21. Paia'Aua
22. Perese
