Australia have written to Rugby League World Cup officials requesting permission to call in a replacement for injured back-rower Luke Lewis for the rest of the tournament.
Lewis' campaign ended after he injured his shoulder slamming into an advertising sign during Saturday's 34-2 win over Fiji in St Helens.
Under tournament rules, teams are usually not allowed to replace injured players but Australia are seeking special dispensation due to the circumstances of Lewis' injury.
A World Cup spokesman told AAP a decision would be made on Tuesday morning (Tuesday night AEDT).
If Australia are allowed to call in a new player, it's likely coach Tim Sheens will seek a like-for-like replacement for Lewis with Beau Scott, Matt Gillett or Ryan Hoffman among those who could be considered.
