PITTSBURGH -- Pittsburgh Steelers assistant coach Joey Porter is rejoining the team in time for Sunday's playoff game in Kansas City.

The team reinstated Porter on Friday morning. The Steelers placed Porter on leave Monday following his arrest on Sunday night during an alleged altercation outside a bar hours after the team's victory against the Miami Dolphins.

The district attorney dropped the most serious charges Thursday after examining surveillance videos. Porter still faces charges of disorderly conduct and summary public drunkenness.

Steelers chairman Art Rooney II said in a statement Friday the team has reviewed the situation and took note when several charges were withdrawn.

Porter added in a statement he is grateful to return to the team and regrets the incident.
