The Hibs – wearing black armbands as a mark of respect to their former player, Mick Lochrie, who passed away earlier in the week - took on the role of party-poopers with a 2-1 victory over champions-elect Downfield.
Importantly for Thornton this kept alive their hopes of joining Downfield in next season’s Premier League.
Ross Morgan put the Hibs ahead with an acrobatic scissors-kick.
Andy Adam increased the Hibs’ lead in the 32nd minute with a fierce drive from outside the area.
James Russell eventually pulled one back.
On Saturday Thornton welcome Kirriemuir Thistle.
On Monday night goals from Young, McCreadie, Duffy, Walton and Morrison helped ease Dundonald Bluebell into the semi finals of the East of Scotland Cup over Armadale.
After making a patchy start to the game Bluebell quickly got themselves onto the front foot and cruised to victory.
This was a great result for Dundonald who have now beaten two Super League teams after seeing off Kelty Hearts in the last round reach the semi finals.
At the weekend Bluebell shared the points in a 0-0 draw with Oakley.
On Saturday they face Dundee Violet at home.
A goal from Connor Kirton helped Kirkcaldy YM to a 1-0 win over Kirriemuir Thistle.
Both teams created few clear cut chances, but a Kirton headed goal midway through the first half secured victory.
On Saturday YM host Kennoway Star Hearts.
