Defeated Collingwood coach Nathan Buckley says a siren controversy wasn’t a factor in his side’s 21-point loss to the Adelaide Crows.

Adelaide forward Josh Jenkins kicked a goal about two seconds after the three quarter-time siren, giving the Crows valuable breathing space in a tight AFL encounter at Adelaide Oval.

The goal put Adelaide 14 points ahead at the last change and was allowed as umpires didn’t hear the siren – but neither did Buckley nor his Adelaide counterpart Brenton Sanderson.

“It wasn’t the difference in the game,” Buckley said.

“Potentially there’s a momentum shift.

“But our defence had failed … we would have been saved six points but it didn’t affect the flow of the game, it didn’t affect the momentum of the game.”

Buckley said the volume of the sell-out 50,051 crowd at Adelaide Oval prevented the siren being heard.

“It was a loud stadium and we’re still learning about this stadium, about how it works and how it presents,” he said.

“I thought we had buzzers in umpires’ pockets and all of that stuff.

“But this is how things evolve. Circumstances occur and you go ‘geez, we could do better than that’ and then we do something about it.”

Crows coach Sanderson said he also didn’t hear the siren.

“But we have got a time cannon down in the coaches box so we knew,” he said.

“There was a chain – bounce, bounce, handball, handball – we were screaming in the box to just kick it.

“We saw the time go to zero when Josh kicked the goal. We didn’t hear the siren though.”

The volume of the Adelaide Oval siren also was contentious in Port Adelaide’s round-seven triumph over Geelong when players and umpires didn’t hear the halftime blast.
