The left-back is an injury doubt as the tournament is set to begin in Germany on Friday.

The Scotland captain left training early on Monday morning and had to be attended by medical staff.

Robertson has been experiencing a tough time with injuries over the past 12 months, but assistant coach John Carver confirmed that the defender should return to training soon.

He was absent for several weeks of the season with a shoulder problem and then an ankle injury.

He will be hoping to quickly recover and take his place when Scotland play Germany on Friday, June 14th.
