Cooper's Whites ensured they avoided the drop to the Championship on the final day of the season through Sunday's 2-1 victory at Brentford which took Leeds above Burnley who blew their lines in a 2-1 loss at home to Newcastle United.
The Leeds captain has now been named in Scotland boss Steve Clarke's 28-man squad for June's huge World Cup qualifying play-off semi-final against Ukraine and potential final versus Wales, followed by three more Nations League games the same month.
Scotland will face Ukraine on Wednesday, June 1 in their bid to book a place at the Qatar World Cup with the winners facing Wales in the play-off final just four days later on Sunday, June 5.
The Tartan Army will then host Armenia in the first of the month's three Nations League games on Wednesday, June 8 before a trip to the Republic of Ireland on Saturday, June 11.
Another away game against Armenia then follows in the month's third and final Nations League game on Tuesday, June 14.
