Reece Walsh is set to have been sidelined for 61 days when Australia face New Zealand at Allianz Stadium next Thursday, leaving the fullback position open to competition.
James Tedesco, 33, is challenging the incumbent for the No.1 jersey at the World Cup, despite his strong performance in Sunday's grand final.
He led the Sydney Roosters to premiership victory in a 19-18 result against the Knights and collected his second Clive Churchill Medal.
Tedesco ran for a grand final-record 388 metres in the match.
Kevin Walters included him in Australia's World Cup squad on Monday. Tedesco missed last year's Ashes series to attend his brother's wedding.
Despite the grand final heroics, his place in Australia's starting fullback role is not assured.
