Dumbarton manager Stephen Aitken has signed striker Eamonn Brophy on a three-month loan deal from Hamilton Accies.
The 19-year-old had a successful loan spell at Queen's Park towards the end of season 2013/14 and also has first-team experience at New Douglas Park.
Brophy, capped by Scotland at U19 level, could make his debut for the Sons in Saturday's Ladbrokes Championship game against Morton at Cappielow.
