The Scottish Cup final between Aberdeen and Celtic had to be temporarily halted at Hampden.
Referee Don Robertson paused proceedings after around 25 minutes in the first half due to a pyro device thrown onto the pitch.
Cameron Carter-Vickers had the ball around the halfway line when Robertson whistled to signal a stoppage to remove the device.
BBC cameras captured footage of a pyro device sparking near one of the corner flags at Hampden.
It appears the device was thrown from the stand housing Aberdeen supporters.
A steward was on the scene quickly to remove the device with the delay in proceedings limited to around one minute.
Commentator Liam McLeod said: "We are going to have to stop play because there is a pyrotechnic has landed by the corner flag. There have been delays to games here because of pyro this season.
"In one case, there was a ten-minute delay for kick-off."
