Stenhousemuir came from behind to claim a dramatic 2-1 victory and stun league leaders Clydebank at Ochilview.
The Bankies looked set to continue their impressive start to the season after taking the lead with their first attack of the game.
Home defender Tommy Graham could only clear a long ball as far as Brian Hamilton on the edge of the box and he hammered the ball passed Muir keeper Gary Gow.
It was the home side, however, who lifted their game after the early setback and began to dominate.
David Wilie came close after good build up from Barry Donald, but his shot was cleared off the line by Rab McKinnon.
Clydebank had the ball in the net again five minutes before half-time but Steve Murray was clearly offside as he fired home.
Clydebank piled on the pressure immediately after the break with Alan Burke firing a shot narrowly wide, and player-manager Tommy Coyne just failing to connect with a close range header.
The Warriors began to come more and more into the game and they deservedly equalised with twenty minutes remaining.
Scott Miller crossed from the right and substitute Issac English was first to react, heading the ball into the top corner of Wylie's net.
The home side laid siege to the Clydebank goal and their perseverance was rewarded two minutes before the end.
Gavin Duncan fired in a ball from the right and English turned and hit a right-foot shot under the diving Wylie to snatch all three points..
