Rangers have made former St Mirren and Cowdenbeath defender Darren McGregor their second summer signing.
Ally McCoist has already added striker Kenny Miller to his squad for next season and 28-year-old McGregor has penned a one-year deal, with a further 12-month option.
The Rangers boss told the club website: "Darren is a player we have always liked and appreciated, as he is a wholehearted, committed and solid defender.
"He is also very quick and we feel he will be a good acquisition. I watched St Mirren a number of times last year and he was a very consistent performer.
"He has good experience and it is a tremendous opportunity for Darren to kick on and progress his career."
