Shimmin will form part of a new Dundee line-up next season
Dundee have signed defender Dominic Shimmin from fellow Scottish First Division side Morton.
Dens Park manager Gordon Chisholm has released a number of players this month, including defender Jim Lauchlan.
The 22-year-old, who had three years at Queens Park Rangers and who made more than 30 appearances for Morton, has joined on a two-year deal.
Shimmin said: "They are the best team in the league. It is the best place for me to develop and reach my potential."
And the centre-half, who joined Morton in the summer of 2008, added of his new team: "The club's ambition matches mine, in the sense that they want to play in the SPL and I want to play in the highest level possible."
Dundee are rebuilding their squad after failing to clinch promotion to the Scottish Premier League last season.
In the past few weeks, the Tayside club have released nine players, told four others they could look for new teams and lost Ryan O'Leary, Andrew Shinnie and Ben Hutchinson when their loan deals expired.
