I don't know every player's injury/form situation, or when some of these guys are due back (obviously a lot of these guys shouldn't be Origin centres even under a worse injury toll), but these are the eligible players who have played centre in 1st grade and/or are reasonably able to play centre/winger if Hodges & Inglis are out. At least all the ones I can say for sure.

These are the 'options' should both first choices be injured. excluding Willie, 9 of these guys have played origin before. 3 of them have played centre in Origin. 2 have played centre for Australia, but are also injured?
