Ross County boss Jim McIntyre has made former Motherwell defender Paul Quinn his latest signing.
The 29-year-old spent several years at Fir Park before moving to Cardiff City in 2009. He then had a spell with Doncaster Rovers but has been without a club since leaving them in August.
The Staggies earlier this week brought in ex-Wolves defender Jamie Reckord, 22, until the end of January while Canadian international midfielder Terry Dunfield, 32, has joined until May.
