Denny Johnstone heads out on loan

The 20-year-old will stay with the Scottish Championship side until June.

Blues, however, do have a recall option in the January transfer window.

Johnstone's move it subject to international clearance.

Johnstone has made two appearances for Blues since joining from Celtic in July 2014 for an undisclosed fee.

The Scottish Under-19 international gained league experience by spending time on loan to Cheltenham Town and Burton Albion last season.
He scored a goal apiece for each side.
