Port Adelaide forward Willie Rioli has been charged by the AFL Match Review Officer following an incident on Sunday evening.

Rioli was charged by Michael Christian for tripping GWS defender Connor Idun during the second quarter of the Power's clash with the Giants on Sunday evening at Adelaide Oval.

It's Rioli's first offence of the sort, resulting in a fixed financial sanction.

Consequently, the livewire goalkicker was slapped with a $1,500 sanction on Monday evening, which can be reduced to $1,000 with an early plea.

Port Adelaide defeated finals-contending GWS by 51 points in a dominant performance; a much-needed victory for the Power after losing its past four matches.

The Power remain perched inside the top four and will be looking to secure a home final in week one of the post-season.

Rioli and Port Adelaide prepare for a Round 23 clash with Fremantle in Perth before returning home in the final week of the regular season to host Richmond.

There were no other charges laid by the MRO from Sunday's three games.
