Moving the ball has been a problem for the Ravens as they fight off both the Vikings and the snow at M&T Bank Stadium.
The Ravens didn't reach the 100-yard plateau until their final possession of the first half and are being outgained 151-103 at halftime. But thanks to Toby Gerhart's lost fumble at his own 25, Baltimore holds a 7-3 lead.
The Ravens haven't advanced past the Vikings' 40 since scoring on their third possession, but haven't let Minnesota do much better. Baltimore forced the Vikings to punt on five of seven first-half possessions, and had a takeaway on one other.
So the defense is doing fine amid the slippery conditions, and might benefit from Minnesota being without its offensive centerpiece. Adrian Peterson left with an ankle injury in the second quarter and his return is questionable. It's not very likely that the Vikings chance his health in the snow, even though the grounds crew appears on pace to having the majority of the field plowed for the second half.
Quarterback Joe Flacco is understandably struggling, going 9-for-22 for 82 yards, a touchdown and an interception so far. He also has 22 of the Ravens' 38 rushing yards on one scramble.
Ray Rice has been limited to 18 yards on eight carries, but also has three catches for 34 yards.
Tight end Dennis Pitta seems to be getting more and more work. He played the entire final series of the first half after playing mostly third downs to open the contest. He has one nine-yard reception in his first appearance of the season.
Update: Blair Walsh's second field goal of the day, a 40-yarder just under three minutes into the second half, has cut the Ravens' lead to 7-6.
The Vikings drove 38 yards in eight plays to set up the kick and make this a one-point game.
