Central defender Coll Donaldson is on trial with Dundee United after being released by Queens Park Rangers.
The 20-year-old's contract was terminated by mutual consent according to the club relegated to the English Championship.
Donaldson made one first-team appearance for QPR after signing from Livingston in January 2014.
The Scot did not play a senior game during the 2014-15 campaign and last featured against Barnsley in May 2014.
Donaldson had one year remaining on his contract at Loftus Road.
He had been transferred to QPR for a fee of around £150,000 after 29 first-team appearances for Livi in the Scottish Championship.
Donaldson has been training at Tannadice this week in an attempt to earn a permanent move to the Scottish Premiership.
