Essendon coach Brad Scott has all but had it with the AFL after multiple requests to clear the umpires from the corridor have been ignored.

Bombers forward Nate Caddy was the latest player to come into contact with an umpire on the far side of the forward 50 as he attempted to make a lead towards the ball, ultimately colliding in his blind spot.

Caddy's incident comes in the same week the league announced a crackdown on careless contact with an umpire, opening the door for multiple offences to be sent to the Tribunal.

Scott, who previously worked inside the AFL house in between coaching stints at North Melbourne and Essendon, said the 19-year-old wouldn't receive a punishment despite the clarified rules.

"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."
