NORTH Melbourne coach Brad Scott left Skilled Stadium on Sunday buoyed by his belief the Kangaroos were able to compete one-on-one with the pacesetters of the competition.

Scott said the Roos simply had to "polish up their game a bit" after allowing Geelong to capitalise on too many errors during the 35-point loss.

"If we make mistakes we're getting punished. The difference between the best sides and the lower ranked sides are that the best sides really make you pay for your errors," he said.

"Geelong did that to us today. They got 11 of their 14 goals from our mistakes.

"If we can just polish up our game and keep working at it, we're headed in the right direction.

"I'd be sitting here really disappointed if I thought we just couldn't compete with them, but I thought we were absolutely able to compete, man for man, so I was pleased about that."

Scott was disinterested in the possession count, which saw Geelong set a record of 505 to the Kangaroos' 372, and was more concerned about the almost-level inside 50 tally.

But he rued the Roos' errors that saw them hand the ball to the skilful Cats on too many occasions.

"On a positive note, we didn't allow them to play the footy they are capable of playing. I thought we were in the game most of the day and we just couldn't quite get close enough to put real scoreboard pressure on them," he said.

"Guys competed really well and that side of things I was really comfortable with. We just couldn't create enough scoring opportunities ourselves."

An accidental collision after a centre bounce between Hamish McIntosh and umpire Damien Sully saw latter come off second best and hobble off the field in the final term.

"I'm concerned about the umpire's welfare as well but surely the other umpire can see that Hamish got blocked. The ball clearly favoured Geelong and it goes down the other end for a scoring shot," Scott said, of the incident.

"Common sense would say you'd recall that bounce."

Young midfielder Jack Ziebell could miss six weeks after an x-ray confirmed a fracture in his tibia - the "other" bone in the right leg he broke last year.

An MRI will confirm the extent of the injury on Monday but the youngster is not expected to require surgery.

Forward Drew Petrie, who was taken through a training session on Skilled Stadium after the game, is rated a "good chance" to return from a broken foot next week.

"Once he's available to join full training and he trains well, we'll make a call on when he plays," Scott said.

"His return is imminent."
