Australian fullback Shannon McDonnell has rejoined St Helens until the end of the 2016 season.
The signing comes 24 hours after New Zealand utility player Lance Hohaia announced his retirement with immediate effect due to "recurrent post match concussion-type symptoms" following his knockout in October's Grand Final.
"It's clear with Jonny Lomax (knee) out for the season and Paul Wellens (hip) currently sidelined, that we need cover at fullback as well as in the backs," Saints chief executive Mike Rush said.
"Shannon can cover a number of positions and we'd like to thank Phil Moss at Wests Tigers and his agent Steve Gillis for making it happen.
"He did a great job last season and we look forward to welcoming him to St Helens once again."
