Former Republic of Ireland Under-21 international Henry McStay has begun a trial with SPL club St Mirren.
The 22-year-old former Leeds, Halifax and Portadown player had a trial spell with Aberdeen two years ago.
Saints boss Gus MacPherson told the club website: "We'll have ex-Leeds United and Halifax player Henry McStay with us for a couple of days.
"He'll be here for us to have a look at him over a few training sessions."
