The start of Gloucester's Premiership game against Worcester Warriors was delayed when a giant inflatable rugby ball broke one of the crossbars.
The incident happened during the build-up at Kingsholm, minutes before the scheduled 14:00 GMT kick-off.
"I was on the radio when I saw about 15 kids trying to push these 40ft by 20ft rugby balls over the posts and much to the hilarity of the fans, who cheered and screamed, the crossbar dropped to the ground. It was the highlight of the day because it was a terrible game."
Ground staff worked quickly to replace the bar but referee JP Doyle decided to put back the start by 30 minutes.
Gloucester won 12-6
for their first home league victory since September, while Worcester are winless in 10.
During the pre-match entertainment, two sets of fans raced from the halfway line to be the first to put their ball over the posts at the Kingsholm Road end of the ground.
But one of the balls somehow managed to push one end of the bar upwards and off its moorings.
With the game due to screened live on BT Sport, Gloucester groundsman Dave Balmer and staff tried to make repairs as quickly as they could.
After nine minutes, an orange tractor drove under the posts for Balmer and a colleague to hitch the bar back into place.
