It's hard to work out what the final 17 might be as there are a few conundrums among the combinations.
I can't see Watson Boas not being in the team so he either has to start or be on the bench.
Jordan Thompson will be a starter so that fills one of the three second row/loose positions.
It's then two from Wilkinson, Jordan Cox, and Brad Foster.
Who covers at hooker? We can't have Ogden, Howden and Jordie on the bench so at least one would have to miss out. If we have Ogden and Jordie as subs (with two props) we've no second row back up and no cover in the wider backs.
Looks like Buchanan will be at full-back with Richard Owen on the wing, with Matty Chrimes. Yere and Tali will be in the centres.
I'd guess Jordan Howden and Brad Foster will miss out as Brandan Wilkinson and Watson Boas will be selected ahead of them.
