Quite predictable really.
So...various options present themselves.
1. Pickersgill moves up to stand off. Brown takes over at fullback and any number of candidates come in on the wing.
2. Jowitt for Lilley.
3. Race for Lilley.
I can see these options all getting a try vs Keighley. I'd go with the first with Jowitt on the bench. Not sure Race is ready to be thrown in against Fev.
