Scotland will be without defenders Kieran Tierney and Scott McKenna for Tuesday’s Nations League clash with Ukraine.

The pair have been left out of Steve Clarke’s squad for the game in Krakow, Poland, along with suspended midfielder Scott McTominay.

Barrie McKay and Stephen Kingsley have been named as the Hearts duo.

Scotland will win Group B1 if they avoid defeat, while Ukraine need three points to finish top.

Arsenal defender Tierney and Nottingham Forest midfielder McKenna both featured in last week’s 3-0 win over Ukraine in Glasgow and Saturday’s 2-1 win over the Republic of Ireland.

However, Tierney was replaced against the Irish after a first-half knock on the head.

Captain Andy Robertson was already missing through injury, and Celtic’s Greg Taylor is likely to fill in at left-back.

Nathan Patterson started at right back against Ukraine but was stretchered off after injuring his knee. His replacement, Aaron Hickey, was dropped after striking against the Republic, but the Brentford player remains with the team.

McKenna played for both matches at Hampden.

Kingsley, a one-time champion in 2016, provides an alternative at left-centre, alongside St Mirren’s Declan Gallagher, who was called up after Wednesday’s win over Ukraine.

With Grant Hanley and Liam Cooper also sidelined, Ryan Porteous is the only other centre-back available to Clarke, but the Hibernian player remains without a cap.

Hellas Verona left-back and Scotland Under-21 captain Josh Doig was signed before the Republic win, but he too has never featured at senior level.

Ryan Jack, Billy Gilmour and Kenny McLean are in contention to replace Manchester United’s McTominay alongside Celtic captain Callum McGregor in midfield, although stand-in skipper John McGinn could be slotted into a deeper position.

McKay’s only appearance for Scotland so far came in the same friendly loss against France in 2016 that Kingsley played in, with the Tynecastle winger coming on as an 88th-minute substitute.
