Dundee United first team squad player Scott Allardice has joined Dumbarton on loan.
The 20-year-old defensive midfielder, who has operated at centre half, has joined The Sons on a six-month loan deal.
Allardice was on loan at East Fife last season and will again play in League One to gain more first team football.
He is set to make his debut tomorrow against Stenhousemuir.
Dumbarton also completed a deal for former Killie midfielder Brad Spencer.
Boss Steve Aitken said: “I cannot thank the sponsors enough. It is very, very much appreciated that we have been backed in this way.
“Brad and Scott are very welcome additions to our squad, especially with injuries being as they are, and we look forward to working with them.”
