PORT Adelaide star Zak Butters has copped a one-match ban for striking, meaning he'll be ineligible for the Brownlow Medal unless he successfully challenges the suspension, while North Melbourne's Kallan Dawson has also copped a week.
Early in the first quarter of the Power's match against Greater Western Sydney on Sunday, Butters engaged in some push and shove with Giants midfielder Tom Green.
The Power midfielder appears to strike Green on the left shoulder with an open hand, with his hand then rising up and collecting Green on the chin.
