CINCINNATI – Rookie running back Giovani Bernard scored his first two NFL touchdowns, one on a short pass he turned into a 27-yard score, and the Cincinnati Bengals beat Pittsburgh 20-10 on Monday night, extending the Steelers’ early-season misery.

The second-round draft pick from North Carolina had a 7-yard TD run in the first half before turning a pass from Andy Dalton into a third-quarter score.

“I saw green grass,” Bernard said. “Once you see green grass, you’ve got to take it.”

The Steelers, scoreless in the second half, fell to 0-2 for the first time since 2002.

An injury-depleted offense couldn’t put drives together consistently, allowing the Bengals (1-1) to wear down their defense.

Cincinnati had advantages in first downs (22-14) and total net yards (407-278).

Steelers quarterback Ben Roethlisberger was 20 of 37 for 251 yards.

“There’s not a lot of positives going on right now,” Roethlisberger said. “We can’t start doubting each other.

“Right now, there’s a general feeling of being upset.”
