Catalans Dragons have signed New Zealand international prop Sam Moa from Sydney Roosters on a two-year deal from the 2017 Super League season.
The Dragons have lost several senior players, including Eloi Pelissier, Romain Navarette and Glenn Stewart.
NRL Grand Final winner Moa, 30, replaces Navarette and the retired Willie Mason who left last season.
"I'm delighted to sign a player of Sam's calibre," head coach Laurent Frayssinous said.
It is Moa's second spell in Super League, having played 78 times for Hull FC between 2007 and 2012.
