Defender Tommie Hoban featured as a trialist for Aberdeen during Saturday’s 1-1 draw with Hibernian.
The Dons are short on options in defence after Mikey Devlin suffered a hamstring injury in a pre-season bounce game against Ross County which is likely to keep him out until September.
Fellow Scotland international Scott McKenna suffered a torn hamstring against St Mirren in the Scottish Cup quarter-final on February 29 which was expected to rule him out for the remainder of the season before Scottish football went into shutdown a fortnight later.
Dons manager Derek McInnes has previously said he does not have scope in his budget to bring in new additions unless a player leaves the club.
Hoban, who is a free agent, was on the verge of landing a short-term deal with the Dons in March prior to lockdown.
