Mitch Robinson was given a one-match ban for striking, while Carlton teammate Marc Murphy was cleared of any wrongdoing in his clash with Nick Riewoldt.

Carlton midfielder Mitch Robinson can accept a one-match AFL ban for punching St Kilda’s Jack Newnes in the head.

Robinson’s jersey was pulled over his head while grappling with Newnes in Monday night’s game, but the 24-year-old still landed a blow.

The match review panel deemed it to be reckless conduct and medium impact, meaning an early plea will result in a one-game suspension for striking.

Meanwhile, the debate over the merits of bumping is set to be replaced with the question of what constitutes a bump after Carlton captain Marc Murphy was cleared.

Nick Riewoldt had his head over the ball when Murphy clattered into him, forcing the shaken Saints skipper from the ground.

But the panel ruled Riewoldt was shoved into Murphy’s path by Blues defender Sam Rowe.

“It was the view of the panel the contact was caused by circumstances outside the control of player Murphy which could not be reasonably foreseen by him,” it said in a statement.

Jack Viney successfully beat a rough conduct charge last week by arguing he was bracing for contact when he collided with Tom Lynch, who was hurtling towards him.

But it was only after Viney lodged a successful appeal, having been found guilty when he was referred directly to the tribunal.

Earlier on Tuesday, Jarryd Roughead accepted a one-match ban that will sideline him from Hawthorn’s top-of-the-table AFL clash with Port Adelaide on Saturday week.

Hawthorn general manager of football operations Chris Fagan said the decision was made after reviewing vision of Roughead’s bump on Sydney’s Ben McGlynn.

“It was pretty clear that part of Rough’s shoulder made contact with Ben McGlynn’s head,” Fagan explained.

“He had 93 carry-over points left from last year’s preliminary final, so without that he would have got off with a reprimand.”

Western Bulldogs forward Liam Jones is out for two weeks after making an early guilty plea for his bump on Melbourne’s Dean Terlich.

West Coast’s Mark LeCras copped a one-match suspension for his bump on GWS’s Will Hoskin-Elliott, while Fremantle utility Paul Duffield got away with a reprimand for the same charge for his hit on Port’s Chad Wingard.

Essendon’s Paul Chapman will miss his side’s Friday night meeting with Sydney after a one-match ban for striking Brisbane’s Dayne Zorko.

From the same match, Lions defender Matt Maguire also accepted a one-game ban for tripping Joe Daniher.
