Barrow pair Liam Paisley and Nathan Mossop will miss the rest of the season with injuries.
Paisley, 21, has made six appearances for the Raiders since arriving from Wigan earlier this year.
The back-rower ruptured his anterior cruciate ligament in the defeat to Sheffield last week.
Paisley will need a knee reconstruction before he prepares for the 2020 season.
Mossop, meanwhile, has picked up a serious shoulder injury that needs operating on.
Barrow face Toronto [away] and Batley [home] in their final two games of the Championship campaign.
