Scrum-half Peter Stringer will join Newcastle Falcons on loan once his deal at Saracens ends next month.
The Ireland international, who is still contracted to Munster, joined the Premiership champions in December to cover a half-back injury crisis.
Stringer will now head to the North East, probably in time for their home game against Harlequins on 12 March.
The 34-year-old will then remain with the Falcons until the end of the season before returning to Munster.
Saracens director of rugby Mark McCall said: "Peter has been a brilliant addition to the squad, on and off the field, and we are sorry his three-month loan spell will come to an end after our match against Northampton on 4 March."
