Kyrell Wilson spins and looks for a Falkirk third, but his wild attempt is over.

A reminder that the draw for the quarters will be coming up here at full-time.

Don't go anywhere.

Stenny look spent here. They've out in some shift to get this to extra time, but those Falkirk goals have knocked the stuffing out of them.

For the final time tonight. Stenny need to find something or their Scottish Cup run is over.
