Former Dundee striker Steven Watson has joined Forfar Athletic, while Dens Park winger Scott Gates has moved to Montrose on loan.
Scott Gates has played for Dundee's first team
Gates, who was farmed out to Forfar last season, will remain with the Station Park side's Third Division rivals until January.
Fellow 19-year-old Watson has moved permanently to Forfar on a two-year deal after being released by Dundee.
Gates played 18 times for Dundee, but Watson failed to make the first team.
