A collision between an umpire and a Carlton player has helped deliver a Brisbane goal in the opening quarter of Thursday night’s clash.

Blues defender Nick Haynes gathered a loose ball on the outer wing and looked inboard to teammate Lachie Cowan.

The kick was going straight to Cowan, but umpire Andrew Heffernan was in the area and inadvertently collided with the Carlton player.

The ball then spilled to Cam Rayner, who handballed on to Charlie Cameron to kick a straightforward goal.

But there’s no doubt Cowan would have marked the ball if it wasn’t for Heffernan.

The incident came a week after Essendon forward Nate Caddy collided with an umpire during last week’s loss to Gold Coast.

Bombers coach Brad Scott was scathing in his assessment of the incident and revealed he had spoken to umpires about getting out of the corridor.

Channel 7 commentator Kane Cornes said this latest incident will be a “big story”.

“Brad Scott says ‘get the umpires out of the corridor’ ... that’s exactly where you want to bring the ball so the umpires have to find a way to get out of where the team want to bring the ball back through,” he said on Channel 7.

“They just have to get their positioning better. We saw it last week with Nate Caddy which was a big story.

“On that occasion, it cost Carlton a goal.”

The Lions quickly added to another goal to skip out to an early 20-point lead, but all the talk was around the umpire collision

“For what it’s worth, I think the umpire gets a fine,” Brian Taylor added.

Cornes continued: “Well, we saw that Nate Caddy had no case to answer. It’s been a big talking point, mainly the umpire contact around stoppages.”

“You can’t have the umpire going right into the corridor when the team’s going to kick the ball back through there.”

Channel 7 commentator Luke Hodge suggested the messaging to the umpires might need to change.

“It’s hard to say (who is at fault). The umpires are positioned where they’ve been told to stand,” he said.

“So it’s just unlucky for the Blues. They will be frustrated. I know the supporters were.

“That’s where the umpires have been told to stand. You think with the collisions we’ve had the last couple of that may be changed at the end of the season.”

Last week, Scott said the umpiring department “refused” to take on his suggestion of getting out of the corridor.

“I’ve lost count the number of times I’ve approached the AFL about moving the umpires out of the corridor. They sprint into the corridor, and they stay there and that’s clearly where we want to get the ball,” Scott said.

“Even when I was at the AFL, I tried to move them down the corridor and they still wouldn’t move out of the corridor. We’ve been at them and at them and at them, to move out of the corridor. And the last response I have from Steve McBurney (head of officiating) was ‘just pretend they’re invisible’.

“Well, he wasn’t invisible, and unfortunately, it actually it took the wind out of Nate Caddy, it took 15 minutes to get him going again. So, you know, whose fault is it? Certainly not Nate Caddy’s.

“Particularly given that we’ve put this on the agenda to move the umpires out of the corridor and they just refused to do it. So I understand the umpire contact around ball ups and that’s a challenge that we’ve got to solve, but, who’s responsible for this? I mean, is it Nate Caddy? Because we lost a player for 15 minutes.

“Not only that, the ARC tells our doctor to go and check on the umpire and assess the umpire. It’s like [shrugs]. And it’s Nate Caddy’s fault? I don’t expect him to have anything to answer for that.”
