Port Adelaide midfielder Sam Powell-Pepper is set to be slapped with a three-game ban following “inappropriate behaviour” at an Adelaide nightclub following the Power's round three win over Brisbane.

According to The Advertiser's Michelangelo Rucci, the AFL are set to officially announce the decision in the next 24 hours, with the League standing behind their integrity unit findings which found Powell-Pepper guilty of “inappropriate behaviour”.

While the ban is a three-game sanction, Powell-Pepper has missed the past two games against Essendon and Geelong while the invitation was taking place, meaning his suspension will be backdated to the start of round four.

That means Powell-Pepper will be unavailable for the Power's clash with North Melbourne this weekend, but is free to play for the Power when they take on West Coast in round seven next weekend.
