Toby R-J. out with a stress fracture of the lower back. I think he was nailed on for a place as a back up seamer in the Ashes squad.
Who goes alongside Broad, Anderson, Stokes and Woakes, in the pace bowling slot?
Can Mark Wood's foot injury heal in time to take the pounding of hard Aussie pitches (must eb a serious risk)
Finn, perhaps? But he has had a poor season up to the last match (by his standards). He does have experience, height and pace, though.
