Second quarter: 49ers 14, Cowboys 7

SAN FRANCISCO -- After the 49ers went up 14-0, the Cowboys had two possessions before the end of the half and eventually scored. The first possession ended with a three-and-out and Tony Romo pointing at Miles Austin about running the correct route. But the second possession resulted in a touchdown thanks to a penalty and a cornerback slipping. On third-and-9, Romo threw a pass toward Kevin Ogletree that was incomplete, but linebacker Ahmad Brooks was offsides, giving the Cowboys life. With only 4 yards to go on third down, Romo found Austin on a slant that went 53 yards for the touchdown. The play was set up when the defender slipped down, giving Austin room. After the catch, Austin put a move on safety Reggie Smith in the secondary and ran untouched into the end zone.

Bradie James' penalty leads to touchdown: The 49ers converted three third-down plays on their first scoring drive of game. But the key play was a Bradie James pass interference penalty on a broken play. On a bad snap, quarterback Alex Smith tracked the ball down and despite being chased he threw a pass toward Frank Gore in the end zone. Smith had his arms draped around Gore's waist when the ball fell incomplete. Gore's 1 yard score, two plays later, registered the first touchdown of the game.

Drops, drops, drops: The Cowboys had three dropped passes in the first half. Austin had two drops and Jason Witten the other. Witten's drop came after he made the catch but took a hard hit, forcing him to lose the ball. Austin had a drop on a deep pass down the 49ers sideline, then while wide open in the middle of the field couldn't hold a route catch. Austin led the Cowboys with 10 drops last season. Austin does have three catches for 66 yards with the touchdown, all coming in the second quarter.

Injuries: Cowboys RB Felix Jones missed a few snaps with a shoulder injury but returned. San Francisco WR Braylon Edwards hurt a knee and he later returned and CB Tramaine Brock also missed some time with a hand injury.
