Keith Galloway and James McManus have withdrawn from Scotland's provisional squad for the Rugby League World Cup, which starts next month.
Wests Tigers forward Keith Galloway is out with a broken foot, while Newcastle Knights' James McManus has a broken leg.
Scotland coach Steve McCormack will name his 24-man squad on 1 October.
The Scots will play Tonga, Italy and the United States in the tournament, which takes place in England and Wales.
Banff-born McManus can play wing, centre or full-back, while prop Galloway had switched allegiance to Scotland having won five caps for Australia in 2011.
McCormack is expected to include three other players from Australasia's National Rugby League in his squad.
Gold Coast Titans prop Luke Douglas, Brisbane Broncos scrum-half Peter Wallace and North Queensland Cowboys centre Kane Linnett could be joined in the pool by Huddersfield trio Danny Brough, Dale Ferguson and Joe Wardle.
