Pittsburgh Steelers linebackers coach Joey Porter was arrested Sunday night outside a Pittsburgh bar, hours after the team's AFC wild-card win over the Miami Dolphins.

Police said security guards at The Flats on Carson summoned a police officer who was working at a nearby restaurant "due to an unruly customer who was in the process of assaulting the doorman."

Police said the officer stopped the assault and arrested the customer, who was later identified as the 39-year-old Porter.

Porter is charged with aggravated assault, simple assault, resisting arrest, public drunkenness and disorderly conduct.

The Steelers acknowledged an "incident involving Joey Porter" in a brief statement Sunday.
