Country Origin captain Danny Buderus has been ruled out of the City Country clash in Mudgee on Sunday through injury.
The Newcastle hooker has been replaced in the starting line-up by Melbourne utility Ryan Hinchcliffe, with Canberra's Josh McCrone brought onto the bench.
Buderus' club coach Wayne Bennett had called on Country selectors to rest the 34-year-old from the match and Country officials expressed concern on Sunday that the NSW Origin veteran would not show up to camp.
The nature of Buderus' injury is yet to be explained.
Buderus has made 21 state of origin appearances, including 15 as captain, but he has not pulled on the blue shirt since leaving Newcastle for English super league outfit Leeds in 2008.
He returned to the Knights, his only NRL club, after the end of the 2011 super league season for what he says will be the final year of his career.
