Dumbarton boss Stevie Aitken has snapped up 22-year-old midfielder David Wilson, who was previously with Partick Thistle.
Wilson spent time on loan at Stranraer last season and now makes the move to the Ladbrokes Championship side on a one-year deal.
He joins fellow summer signings Andy Dowie (Queen of the South), Mark Stewart (Raith Rovers), Tom Walsh (Limerick), Scott Gallacher (Hibernian) and Craig Barr (Raith Rovers) at the Sons for 2017/18.
