England prop George Burgess will miss November's three-match Test series with New Zealand because of a hip injury.
The 23-year-old younger brother of dual-code international Sam Burgess is to have surgery that will rule him out until the start of the 2016 season.
George, who plays for NRL side South Sydney, played five times at the 2013 World Cup and started all three games in the 2014 Four Nations Series.
"George is devastated," said England coach Steve McNamara.
"He needs surgery on his hip and it's going to be a fairly long recovery period for him - about four months.
"He's extremely proud about playing for England and it's been a tough decision for him, but it's one that he's had to make because of the nature of the injury.
"He has to have it done for the rest of his career, otherwise he starts putting himself at risk of further injury."
England play a friendly against France on 24 October, before the three Tests against New Zealand on 1, 7 and 14 November.
