Slovakia ended Scotland's nine-match unbeaten when a first-half goal from Jan Gregus gave them a 1-0 win in their Nations League match on Sunday between teams who both qualified for Euro 2020 amid drama last week.
Gregus scored his fourth goal for his country with a deflected shot in the 32nd minute to deny Scotland a chance to win League B Group 2, and promotion to the top league, with one match to spare.
Scotland, who won a penalty shootout against Serbia to qualify for Euro 2020, nearly equalised with the last kick of the game when Leigh Griffiths got in behind the Slovakia defence but goalkeeper Marek Rodak got his fingertips to the ball.
