Former Hibernian midfielder Guillaume Beuzelin has been confirmed as Dumbarton's new assistant manager.
The Frenchman, who played alongside Sons boss Ian Murray at Hibs, had been coaching youth players at Easter Road and working with the SFA.
Jack Ross recently left the role of assistant manager at Dumbarton to join Hearts as their under-20s coach.
Beuzelin played for the Easter Road side for four years before heading to Coventry in 2008.
He also made four appearances for Hamilton Academical in 2009.
