Rangers have taken former Kilmarnock and Hearts defender Ismael Bouzid on trial.
The 30-year-old Algerian, who has 13 caps for his country, made four appearances for Scottish Premiership side Killie last term.
During a two-year stint at Hearts from 2009-2011 he played 64 times.
Rangers manager Ally McCoist will assess Bouzid, who can play at right back or centre-half, over the next few days.
Midfielder Kyle Hutton also signed a new one-year deal after his contract expired at the start of the summer.
