WHAT WENT RIGHT
* The Steelers were looking at an opening possession three-and-out, but while in the process of sacking Ben Roethlisberger, OLB Courtney Upshaw lowered his head and led with his helmet. The 15-yard penalty gave the Steelers a first down.

• Punter Brad Wing helped the Steelers flip the field early in the second quarter, when he got off a 47-yard punt, and Jacoby Jones signaled for a fair catch at the Ravens 24-yard line.

• Le'Veon Bell made some significant contributions to the Steelers' drive late in the second quarter that ended with a Shaun Suisham field goal to cut the Ravens lead to 10-3. Bell carried three times for 24 yards and caught a shovel pass for 19 more.

• On the Baltimore possession following the Steelers' field goal, the defense recorded a three-and-out. Two Ravens' running plays lost a combined 3 yards, and then Joe Flacco threw incomplete on third down. The ensuing punt gave the Steelers the ball at their 27-yard line with 1:40 left in the half and three timeouts.

• The Steelers defense started the second half strong. After a holding penalty on Jeremy Suttah set up a first-and-20 for the Ravens at their own 10-yard line. Baltimore didn't gain a single yard on the next three plays, and Antonio Brown returned the punt to the Pittsburgh 48-yard line.

WHAT WENT WRONG
* It was an 18-yard completion from Ben Roethlisberger to Antonio Brown, and it converted a third-and-14, but on the play Ravens safety Darian Stewart drove his shoulder into Brown's upper torso. Brown left the game to be evaluated for a possible concussion.

• On a second-and-9 from the Baltimore 22-yard line on the Steelers' opening possession, Ben Roethlisberger completed a quick pass over the middle to Justin Brown, who had the ball stripped by Daryl Smith, and DeAngelo Tyson recovered for the Ravens at the Baltimore 16-yard line.

• On the Ravens' first play after recovering the fumble, Cortez Allen was flagged for grabbing Steve Smith's facemask following a short pass, which ended up moving the ball to the Baltimore 45-yard line.

• It was a third-and-5 from the Pittsburgh 26-yard line, and Joe Flacco went deep down the right sideline to Torrey Smith. Cortez Allen committed an obvious pass interference penalty, and the Ravens ended up with a first-and-goal from the 3-yard line.

• On a second-and-goal from the Pittsburgh 2-yard line, the Steelers were deployed in a 4-6-1 defensive alignment to counter the Ravens, who had multiple tight ends and a fullback on the field. On play-action, Terence Garvin lost TE Owen Daniels, who was all alone in the end zone for an east touchdown that gave the Ravens a 7-0 lead with 27 seconds left in the first quarter.

• On a second-and-9 from the Pittsburgh 21-yard line early in the second quarter, the Steelers ran a jet-sweep, and Markus Wheaton burst through a hole for 21 yards. But the hole was created with the help of a hold by Darrius Heyward-Bey, and the ball went back to the 24-yard line.

• With less than one minute left in the first half and the Steelers having a first-and-10 at the Baltimore 42-yard line, Elvis Dumervil beat Marcus Gilbert to sack Ben Roethlisberger for an 8-yard loss. Two plays later, on a third-and-four, Gilbert was flagged for a false start that set up a third-and-9. The Steelers ended up having to punt.

• What looked like a promising possession for the Steelers early in the third quarter ended with a 43-yard field goal and a sense of a squandered opportunity. On a second-and-5 from the Baltimore 21-yard line, Elvis Dumervil put Marcus Gilbert on his back and sacked Ben Roethlisberger for a 7-yard loss.

• With help from some questionable calls for hits on defenseless receivers, the Ravens drove 80 yards in 12 plays for the touchdown that upped their lead to 17-6 with 3:58 remaining in the third quarter. On both penalties – one called on Troy Polamalu and one called on Mike Mitchell – the defensive player used his shoulder to make contact with the receiver in the torso area. The touchdown came on another short pass to Owen Daniels, who again took advantage of a busted coverage to be wide open.

• Through three quarters, the Steelers had been penalized eight times for 73 yards. The Ravens had been penalized twice for 25 yards.

• On the first play after the Ravens field goal that upped their lead to 20-6, a short pass to Heath Miller turned into a turnover when the ball was stripped loose and recovered by C.J. Mosely. The Ravens took possession at the Steelers' 20-yard line.
