Pittsburgh Steelers assistant coach Joey Porter was arrested on Sunday night, only hours after the team's 30-12 victory against the Miami Dolphins. On Monday, the Steelers placed him on leave.

"We are continuing to gather information concerning Sunday night's incident involving Joey Porter," said general Steelers general manager Kevin Colbert in a statement. "We have been and will continue to be in communication with the NFL as is required by the Personal Conduct Policy. Pending further review, Joey Porter has been placed on leave. At this time, we will move forward with our preparations for the Divisional Round playoff game at Kansas City."

A Pittsburgh Public Safety spokesperson told KDKA, the CBS affiliate in Pittsburgh, that Porter was detained late Sunday after getting into an altercation outside a local bar. According to a police statement obtained by WPXI.com in Pittsburgh, police were called to the bar after it was reported that an unruly customer was "in the process of assaulting a doorman."

After being taken into custody, Porter was hit with a total of five charges, including aggravated assault, simple assault, resisting arrest, public drunkenness and making terroristic threats.

The 36-year-old Porter is in his third season as a Steelers assistant, and in his second year as the team's outside linebackers coach. Porter also played 13 years in the NFL, with eight of those coming in Pittsburgh.

Porter is famously known for coming on the field during the Steelers-Bengals playoff game in January 2016. His presence caused a melee, which led the NFL to enact the "Joey Porter rule" for the 2016 season. Under that rule, assistant coaches are not allowed to enter the field of play at any point during a game.
