Dundee have signed former Everton and Stoke goalkeeper Steve Simonsen.
The 33-year-old, who left Preston in January, has signed until the end of the season and is available for Sunday's Dundee derby.
John Brown has recruited Simonsen to provide competition for current number one Rab Douglas.
Dundee are currently bottom of the SPL table, trailing 11th-placed St Mirren by 14 points.
Simonsen made 17 appearances for League One Preston after moving to Deepdale on a free transfer in August 2012.
The former England U21 keeper also enjoyed spells at Everton, Stoke City and Sheffield United.
