Canterbury-Bankstown Bulldogs half Kieran Foran will require reconstructive surgery on the shoulder that he injured while representing New Zealand at the weekend.
Foran had scans on his shoulder yesterday and will now require initial exploratory surgery to determine the full extent of the injury.
The recovery for the surgery is expected to be at least six months and could be longer depending on the results of the initial surgery.
"The news is incredibly disappointing for both Kieran and the Bulldogs, especially as he has worked so hard to get back on to the field," said Bulldogs Chief Executive Andrew Hill on the club website.
"The club will make sure that Kieran receives the best possible medical support during surgery and his rehabilitation and will continue to monitor his recovery and potential return date.
"Kieran is part of the Bulldogs family and we will make sure that he and his family receive everything they need during this time."
