Port Adelaide will be without Junior Rioli for the next two rounds after he was suspended by the AFL tribunal.
Rioli had been referred straight to the tribunal for striking Essendon's Jordan Ridley during the Power's five-point win at Adelaide Oval on Sunday.
The match review panel had classed the impact as severe, however, the tribunal on Wednesday night downgraded it to high.
He had been offered a three-match suspension by the match review panel.
Rioli will miss matches against the Kangaroos and Demons.
He collected Ridley high after sticking out his arm in a clumsy attempt to block for a teammate.
A dazed Ridley fell to the ground and was subbed out of the match with concussion in the second quarter.
Ridley will miss Essendon's match against the Brisbane Lions at the Gabba on Saturday night.
After deliberating for 30 minutes, the tribunal deemed the force of Rioli's strike was high.
"Rioli's intention was to block and not strike him (Ridley), he delivered a blow with his hand or arm," AFL tribunal chairman Jeff Gleeson said.
"On one view he was unfortunate but moving his arm the way he did meant that he was careless to whether he committed a strike."
Port Adelaide's lawyer Paul Ehrlich claimed Rioli did not strike Ridley as he was attempting to shepherd the Bombers backman.
"We say unfortunately because the arm (of Rioli) was up, Mr Ridley ran into it," Ehrlich told the tribunal.
"The fact there is a concussion doesn't mean the impact was severe."
Ehrlich used several examples during his lengthy argument, saying the contact Rioli made to Ridley was far less impactful than other incidents during recent seasons.
The AFL's counsel Lisa Hannon said Rioli delivered a "blow with some force" while he was running and off the ground.
"It doesn't matter if it was in a blocking motion, there doesn't need to be a swing to be a strike," she told the tribunal.
Ehrlich even brought up Sydney Swans great Barry Hall's infamous punch on West Coast's Brent Staker 15 years ago when arguing his case.
Rioli, a West Coast premiership player, has featured in all eight matches for the Power this season after his move to Alberton at the end of last year.
