Northampton Town have signed former Crewe Alexandra defender Gregor Robertson until the end of the season.
The 30-year-old defender joins the Cobblers following his release by Alexandra last month, where he was the club's first-choice left-back last season but fell out of favour this term.
He could make his Cobblers debut in Saturday's home match against Plymouth Argyle.
The East Midlands club are rockbottom in the Football League, six points adrift of safety in League Two.
