Adelaide's key forward Taylor Walker, St Kilda star Brendon Goddard, Hawthorn defender Brent Guerra, Essendon half-forward Stewart Crameri and Richmond on-baller Daniel Jackson have all incurred the wrath of the AFL's match review panel.

In the most talked-about case, Walker was found to have engaged in rough conduct against Richmond defender Steven Morris, and has been offered a three-match suspension on a guilty plea by the MRP. It is his second similar incident this year; he was rubbed out for two matches for a sling tackle on Geelong’s Harry Taylor earlier in the season.

The Crows will ponder whether to take the matter to the tribunal but because of the points allocated, the suspension cannot be reduced any further, and they would have to prove that he was not guilty. As it was, the MRP had to add carryover points and the suspension was four matches, reduced to three on a guilty plea.

Walker has been a pivotal figure in Adelaide's rise this season with 37 goals. But his actions have been condemned in the media, with former Western Bulldogs’ ruckman Luke Darcy calling his spearing tackle on Morris "dangerous".

Meanwhile Goddard’s difficult week — he was tagged out of the game by North Melbourne’s Sam Wright at Etihad Stadium on Sunday — got worse when he was offered a two-match suspension for striking his opponent.

The St Kilda utility was assessed as having made intentional contact with Wright during an off-the-ball incident. The MRP rated the incident as meriting a three-match suspension, reduced to two matches on a guilty plea.

Hawthorn's Guerra fell foul of the crackdown on head high contact, having cannoned into Carlton’s Eddie Betts a the MCG last Friday night as the Blues’ forward stooped to pick up the football. The MRP assessed Guerra’s action as reckless and contact as medium. It brought a four-match suspension, reduced to three if the Hawks choose to offer a guilty plea tomorrow.

Crameri, a revelation up forward for Essendon this season, seems set to sit out two matches after he was found to have engaged in rough conduct against Dylan Addison of the Western Bulldogs. The MRP assessed the collision as negligent with high impact, bringing a three-match suspension that can be reduced to two with a guilty plea.

Jackson was found to have committed a level two striking offence against Chris Knights of Adelaide Crows on Saturday, and his initial one-match suspension was doubled because of a poor record.
