Pittsburgh outgained Buffalo 239-50 — including 155-9 on passing yards — in the first half. The Bills were without injured defensive regulars Ko Simpson, Coy Wire and Jason Webster. But the Steelers couldn’t get into the end zone until late in the third quarter on Roethlisberger’s second TD pass in as many games to rookie tight end Matt Spaeth. Roethlisberger was 21-of-34 for 242 yards and one interception.

“We kept putting 3s on the board, but at least we were doing that while we ran the clock off,” guard Alan Faneca said. “We definitely would have liked to get in the end zone a couple of times. It stings a little bit when you’re only putting 3s up.”

Through two Steelers victories, Roethlisberger has five TD passes and an interception. A year ago, following a motorcycle crash and an appendectomy, he had five interceptions and no TD passes while losing his two starts.

Losman had only two completions for 5 yards until late in the third quarter. He finished 15-of-25 for 154 yards.

A week after Everett was hurt, the Steelers got a scare of their own when outside linebacker James Harrison lay motionless on the field with a neck injury for several minutes at halftime. But he was back on the sideline, walking freely, midway through the third quarter, and tests showed no serious problems.

“It made you a little nervous after what happened last week,” defensive end Aaron Smith said.
