North Melbourne coach Alastair Clarkson says the club is "extremely disappointed" with comments made by the AFL during the week that match review gradings could potentially be reviewed at the end of the year.

The rigid match review model has been a contentious talking point all week following the three-match suspension to Kangaroos forward Paul Curtis for his tackle on Port Adelaide's Josh Sinn in round seven.

The League's footy boss, Laura Kane, made comments on radio during the week suggesting that this incident may lead to the severity of suspensions being changed before next season.

"It doesn't make sense that the AFL come out and say, 'Oh we might change that at the end of the year'," Clarkson said following his side's three-point loss to Essendon on Thursday night.

"It doesn't help us. We're really disappointed with that, really disappointed. Because really strong leadership would say, 'We understand it's wrong, and we'll change it right now'.

"He (Curtis) shouldn't be missing three weeks of footy."

Curtis would have been a handy addition to the Kangaroos in the heartbreaking loss after they challenged Essendon for most of the match. 

Asked whether he missed having his small forward out there against the Bombers, Clarkson spoke to Curtis' strong start to the season before continuing with his disapproval of the suspension.

"He's been pretty good for us this year, he's kicked 18 goals in seven games," he said.

"It's not just what he can do offensively for us, as we saw in last week's game particularly against Port Adelaide, but right throughout the course of the year. 

"In my view, he's nearly the best tackler in the competition. It's a shame that that part of our game is getting questioned, it's a feature of our game.

"We understand there's a duty to care, but there's a duty of care to the game."

The Roos have a 10-day break before their Round 9 match, when they face Brisbane in Hobart next Sunday.
