There were serious concerns over the Arsenal left-back after he limped out of a defeat to Liverpool earlier this month with damage to his knee ligaments.
Thankfully for the former Celtic star, surgery was not required with his club initially setting an expected recovery time of around mid-May.
Doubts were cast around that diagnosis with Gunners boss Mikel Arteta seemingly hinting that Tierney would miss the rest of the campaign.
However, it’s now been revealed the 23-year-old has made “positive progress” and could feature again before the end of the domestic season.
An update from Arsenal read: “Kieran sustained ligament damage to his left knee during the match against Liverpool on April 3. Kieran continues to make positive progress and is hoping to be back in training within two to three weeks.”
Such a timescale would give Tierney the chance of playing another competitive match or two before the Euros.
If fit, the left-sided defender is a certainty to make Clarke’s squad. The former Parkhead favourite was the star man in the 4-0 victory over the Faroe Islands last time out, notching up three assists as the national team got their first victory of the World Cup qualification campaign.
The opening match against the Czech Republic takes place on June 14. Scotland have scheduled warm-up friendlies against Luxembourg and the Netherlands prior to the tournament.
