Whitehaven have signed French prop Thibault Alency from Lezignan for the remainder of the 2015 season.
Alency, 27, is the third French signing for Haven this term, following moves for St Esteve pair Louis Jouffret and Jordan Sigismeau.
"This will give us more strength as we move towards the Super Eights," general manager Amanda Hewer said.
Sigismeau has now returned to his parent club and will go into the Catalans Dragons Super League squad.
Haven are eighth in the Championship with four games to play before the top two tiers split into three.
The bottom eight Championship clubs will compete for the Championship Shield, and to avoid relegation from the second tier.
