Pittsburgh Steelers safety Troy Polamalu has admitted that he is aware of the threat that Buffalo Bills quarterback EJ Manuel can pose on the ground.

Polamalu was part of the Steelers side that allowed Terrelle Pryor of the Oakland Raiders to break an NFL record when he rushed for a 93-yard touchdown against them last month.

Polamalu told the Pittsburgh Tribune-Review: "Any time you have someone who can run and pass, it gives them flexibility with their play calling.

"We have to be aware of Manuel scrambling. As a team, we have to get off to a good start.

"If they want to beat us, they have to control the ball. If they establish the running game, it'll be a tough game for us."

Both the Steelers and the Bills sit at the bottom of their respective divisions in the AFC.
