The Pittsburgh Steelers filed a complaint with the NFL in response to a claim that Miami Dolphins defensive tackle Ndamukong Suh intentionally kicked quarterback Ben Roethlisberger in his right knee during a recent game against the Dolphins.

The play occurred in the fourth quarter while Suh was engaged with guard David DeCastro. Suh appeared to extend his leg in the direction of Roethlisberger, striking him in the knee.
