Q: Passage: The Steelers opened up their regular season on the road against their old AFC North division rivals, the Baltimore Ravens. The Ravens scored quickly on their first drive, when only three plays into the game, Baltimore wide receiver Anquan Boldin caught a 27-yard touchdown pass from quarterback Joe Flacco. The Ravens scored again on the ensuing drive when running back Ray Rice ran in a 1-yard touchdown, putting Baltimore on top 14-0 early in the first quarter. The Steelers battled back on the next drive, driving down to the Ravens 11-yard line. Pittsburgh scored on a third-and-goal play when wide receiver Emmanuel Sanders caught a touchdown in the back of the end zone from quarterback Ben Roethlisberger. The Ravens responded by scoring again, this time on an 11-yard pass from Flacco to Rice. At halftime the Ravens led 21-7, just like in the 2010 playoffs. But unlike that game, the Ravens did not let up their dominance in the second half. On Pittsburgh's first play from scrimmage in the second quarter, Ravens defensive lineman Haloti Ngata stripped Roethlisberger of the football and recovered it at the Steelers 18-yard line. The Ravens scored yet again when tight end Ed Dickson caught an 18-yard touchdown pass from Joe Flacco. A two-point conversion by punter/holder Sam Koch put the Ravens on top 29-7. The Ravens never looked back, and put up two more Billy Cundiff field goals to close out the game 35-7. The Steelers finished with 7 turnovers in the game. The loss marked the Steelers first opening day loss in 8 years, and left Pittsburgh at the bottom of the division with an 0-1 record.
