Dumbarton have signed full-back Mark Wilson following his recent departure from Dundee United.
The 30-year-old former Celtic defender, capped once for Scotland, has agreed a deal with the Championship side until the end of the season.
Sons boss Ian Murray, whose side host Cowdenbeath on Saturday, told the club website: "Mark has plenty of experience, having played at the top level in Scotland. He will do well for us over the remaining games in the season."
