PITTSBURGH (AP) An Oakland Raiders linebacker is being investigated to determine whether he illegally taunted a police dog before a game in Pittsburgh against the Steelers.

Television station WTAE in Pittsburgh says a sheriff's deputy working with the dog Sunday identified the player as Ray-Ray Armstrong.

Chief Deputy Kevin Kraus says a player lifted his shirt, beat his chest and barked at the K-9 before telling a deputy to release the dog. The deputy didn't release the dog.

He tells The Associated Press the player was in uniform heading to the field. He says a decision on charges could come this week.

Armstrong, the Raiders and the Steelers declined comment Tuesday.

Taunting a police dog is a third-degree felony in Pennsylvania.

Kraus says surveillance video captured part of the encounter.
