Dickson caught a 1-yard touchdown in the first quarter from Flacco during a day where tight end Dennis Pitta played in his first game of the season since being activated from injured reserve-designated to return and scored a touchdown in the fourth quarter.

"The fact that Dennis was back made that happen," Dickson said. "Usually, Dallas Clark would be in there. I got to be physical on the goal line. Then, they called a pass play. Joe threw it up, and I took advantage of it. That got us started and we held that lead for a long time."

Dickson's last touchdown until Sunday came in a Dec. 24, 2011 game against the Cleveland Browns.

"I haven't scored a touchdown in almost two years," Dickson said. "Hopefully, it will open the flood gates."

Peterson injured

It was a rough day for Viking star running back Adrian Peterson.

Peterson was carted off the field in the first half with a sprained right foot  suffered during a first-half tackle by Ravens rookie linebacker Arthur Brown and was ruled out for the remainder of the game. He’ll undergo a magnetic resonance imaging exam Monday morning, according to coach Leslie Frazier.

"Adrian Peterson, I wish him a speedy recovery," running back Ray Rice said. "I'm not sure the extent of the injury, but he is somebody I look to for inspiration."

Peterson entered the game as the NFL’s leading rusher with 1,208 yards and 10 touchdown runs, but was limited to 13 yards on seven carries Sunday by the Ravens’ sixth-ranked run defense.

He was replaced by running back Toby Gerhart, who rushed for 89 yards and a touchdown on 17 carries.

"They're both big, physical running backs," defensive lineman Arthur Jones said. "Gerhart is a guy who doesn't stop running his feet. I missed a few tackles myself that could have changed the outcome of the game. They're definitely two good backs."

After the game, Peterson complained about the officiating and said the Ravens’ fans threw snowballs at him.

“Wow talking about bad officiating & the worst fan base I've ever experience!” Peterson wrote on his official Twitter account. “They threw snow balls the entire 4q like lil kids. Smh.”

Fumble reviewed

The Ravens' first touchdown was set up by a fumble in the first quarter by Gerhart that was upheld following a replay challenge.

"I didn't seen enough to overturn the ruling on the field as a fumble," referee Pete Morelli told a pool reporter.

Gerhart appeared to have his knee down, but it was inconclusive enough that the play wasn't overturned.

"I felt like I had both knees down, and, unfortunately, they saw it different," Gerhart said. "I felt like I had both knees down, and I was just kind of going down to the ground and he ripped it out at the last second and that's the way it goes."

Rookie free safety Matt Elam recovered the fumble that was forced by strong safety James Ihedigbo.

"They told me it was too close to overturn," Frazier said. "Our guys upstairs thought it was clear that his knees were down."
