Celtic left-back Kieran Tierney is out of Scotland's clash with San Marino on Sunday.

The 21-year-old was also missing for Thursday's 3-0 defeat to Kazakhstan in Astana.

The national team has now confirmed that he wont travel with the squad to San Marino and will return to Scotland instead.

Liverpool's Andrew Robertson was also missing on Thursday meaning Aberdeen captain Graeme Shinnie filled in at left back in the opening game of the Euro 2020 Qualifiers.

Celtic fans will be hoping Tierney, who has missed several games since the turn of the year, will recover in time for their game against Rangers at Celtic Park on March 31.
