SYDNEY premiership coach Paul Roos has declared his major confusion over Taylor Walker’s “mind-boggling” one-week suspension.

The Adelaide captain will miss just this week against Brisbane after being handed a one-game ban for rough conduct, based on an incident with Geelong star Zach Tuohy.

Walker ran past the ball and appeared to be looking at his Cats opponent when he collected Tuohy with his elbow. The incident was graded by match review officer Michael Christian as careless with medium impact.

“I’m staggered. This is the most mind-boggling decision Michael Christian has made all year,” Roos said on Fox Footy’s On the Couch.

“I generally go with my gut feeling, and I thought he’d be copping three (weeks) if you’re lucky. He runs past the ball, hits the guy in the head.”

Roos showed a number of other incidents that also received a one-week suspension as a sanction which he said were actually deserving of that penalty.

“That’s accidental. Same penalty. That’s a stomach punch. Same one-week penalty. These deserve one week,” he said.

“This is trying to get some consistency around the Match Review.”

Melbourne great Garry Lyon agreed with Roos while taking umbrage with the grading of careless.

“We can see it. Tex is looking at Zach. He’s not looking at the ball, he’s looking at Zach!” Lyon said.

“There’s no carelessness about that, that’s an intentional act anyway you sum it up.”

Roos then argued the issue was with how Christian made his decisions based more on what resulted from the incident than what was actually done by the offending player.

“It’s the outcome, it’s not the actual action any more. If you’re going to hit someone, hit someone with a hard helmet,” Roos said.
