Newly promoted Falkirk earned their first top-flight victory in 15 years as they saw off 10-man Aberdeen to leave them bottom of the Scottish Premiership.
While the visitors would have been fresh after having last weekend off, the hosts stepped out in the Granite City hoping there was no physical or mental hangover following their midweek Europa League play-off defeat to FCSB in Romania.
Aberdeen had the better of a first half which saw a whirling wind make life difficult for both sides.
The Dons created several decent chances, with Falkirk keeper Scott Bain having to produce good saves to deny Topi Keskinen twice and Nicolas Milanovic.
At the other end, Bain's Aberdeen counterpart Dimitar Mitov did well to turn a powerful Brad Spencer shot wide.
As the interval approached, the home side were reduced to 10 men when Nicky Devlin was sent off following a robust challenge on Calvin Miller.
Devlin was initially booked, but that was upgraded to red after referee Ross Hardie was called to the monitor by the video assistant referee (VAR).
With the extra man advantage Falkirk took charge after the break.
Mitov produced good saves to deny Dylan Tait and Scott Arfield, while Spencer had an effort cleared off the line.
So it was no surprise when the visitors took the lead. Substitute Kyrell Wilson, a recent arrival from Swansea City, drilled the ball into the net on 74 minutes to secure the three points for John McGlynn's side.
