Polamalu leaves game with head injury

Steelers safety Troy Polamalu has left Sunday night’s game against Kansas City after his head banged into the knee of offensive tackle Steve Maneri.

The team said Polamalu had a ”blow to the head” and would continue to be evaluated.

The 6-foot-6, 290-pound Maneri had lined up in the backfield as an eligible receiver and hauled in a short pass from Tyler Palko. Polamalu came up to make the tackle and dove at Maneri’s legs, his head banging into the big offensive tackle’s knee.

Polamalu, who had been dealing with some sore ribs, looked a bit wobbly as he got up. He was helped to the sideline by trainers and did not return on the Steelers’ next defensive series.
