CINCINNATI — The Steelers haven't opened a season so badly in 11 years.
Rookie running back Giovani Bernard scored his first two NFL touchdowns, and Pittsburgh's offense had trouble getting first downs as the Cincinnati Bengals pulled away to a 20-10 victory on Monday night.
For the first time since 2002, the Steelers are off to an 0-2 start.
"We have work to do," coach Mike Tomlin said. "We aren't going to hide from that fact. We are going to embrace it and accept it, and understand that there is some misery that comes from the position we are in right now."
There's plenty of misery to embrace.
The Bengals (1-1) piled up 407 yards on one of the NFL's toughest defenses, holding the ball for more than 35 minutes. On offense, the Steelers had another game full of self-destruction, turning the ball over twice in scoring range.
Pittsburgh failed to get a first down on seven of its 12 possessions, giving the defense little time to catch its breath.
"There's not a lot of positives going on right now," said Ben Roethlisberger, who was 20 of 37 for 251 yards with one touchdown and a deflected interception. "We can't start doubting each other. Right now, there's a general feeling of being upset."
It was a chance for the Bengals to show they've supplanted the Steelers in the AFC North. They beat Pittsburgh 13-10 at Heinz Field last December to reach the playoffs, and now have moved ahead of them again with a rare Monday night win.
Cincinnati is 10-20 in Monday night games.
"This doesn't define anything until you look back at the end of the year," coach Marvin Lewis said.
Two Cincinnati rookies made the difference, putting their new imprint on an old rivalry.
Top pick Tyler Eifert made a 61-yard catch that set up Bernard's 7-yard run for his first NFL touchdown. Together, they gave a preview of what the Bengals could become with two new pass catchers in the offense.
The Bengals put the ball in the Andy Dalton's hands in the first half, letting him pass away while they all but abandoned the run against one of the NFL's top defenses. Dalton had an up-and-down game, finishing 25 of 45 for 280 yards.
Cincinnati's rookies provided the big plays.
Eifert got open between cornerback Ike Taylor and safety Ryan Clark for his 61-yard catch. Bernard finished the long drive with a 7-yard run, his first touchdown in the NFL, for the early lead.
The Steelers needed to get their offense moving after a horrid opener. They ran for only 32 yards and Roethlisberger was sacked five times during a 16-9 home loss to Tennessee. Worse, the Steelers lost Pro Bowl center Maurkice Pouncey for the rest of the season with a torn knee ligament. Fernando Velasco, signed a week earlier, started in his place Monday.
They weren't significantly better in Cincinnati, managing only 44 yards on the ground.
"We've played two and lost two," running back Isaac Redman said. "That's as big of a hole as you can get. It don't look like Steeler football out there."
Roethlisberger got Pittsburgh's offense moving in spurts. He completed all five of his passes on a touchdown drive that pulled the Steelers into a 10-all tie at halftime, including completions of 19 and 43 yards to Emmanuel Sanders.
Shaun Suisham kicked a 44-yard field goal, and the Steelers had a chance to add to the lead in the first half. But another mistake — and they've had a lot of those already — provided the game's first turning point.
Pinned at their 3-yard line after a punt, the Steelers drove into scoring position. Roethlisberger completed a 34-yard pass to tight end David Paulson, who fumbled the ball as he was tackled. Adam "Pacman" Jones forced the fumble and recovered it at the Cincinnati 13-yard line.
Another of Roethlisberger's passes went off Jerricho Cotchery's hands and was picked off at the Bengals 13-yard line in the fourth quarter, essentially sealing it.
The most intriguing question: Could Steeler-turned-Bengal James Harrison leave a mark on Pittsburgh's mess of an offense?
Nope. He didn't have a sack or a tackle.
Notes: The Bengals rushed for 127 yards, with BenJarvus Green-Ellis getting 75 on 22 carries. Bernard ran eight times for 38 yards. ... The Bengals have consecutive wins over the Steelers for the first time since 2009. ... Roethlisberger was sacked twice by a defense that failed to get one in Chicago. ... Redman missed much of the first half while getting tested to see if he got a concussion. He was cleared to return and carried three times for four yards.
