Midfielder Eggert Jonsson and defender Dan Seaborne have joined Charlton Athletic on one-month loan deals.
Jonsson has moved to the Valley from Wolverhampton Wanderers after falling out of favour with manager Stale Solbakken.
Saints defender Seaborne has only featured in the League Cup this season and he has been handed a move to Charlton to play competitive football.
Both players will be available for Charlton's match with Bristol City on Sunday.
