"Everybody just stuck together and stayed positive and continued to play the way we normally do," Williams said. "Eventually, Tom Brady made a couple of mistakes and we were able to capitalize on them."
Brady completed 29 of 54 passes for 320 yards and a touchdown, surpassing Brett Favre and moving into first place on the NFL's career postseason list with 5,949 yards passing. He is 4-1 against the Ravens in the regular season and 1-2 in the playoffs.
The Ravens are the only team he's thrown more interceptions against (10) than touchdowns (eight).
The Patriots, who had the highest-scoring offense in the NFL this season, were held to a season-low point total in their finale — more than 20 below their average.
Welker had eight catches for 117 yards, and Stevan Ridley ran for 70 yards on 18 carries before leaving the game following a fourth quarter carry in which Bernard Pollard hit him in the head so hard that he fumbled away the ball.
"That was the turning point of the football game there on the 40-yard line," Ravens coach John Harbaugh said. "It was a tremendous hit. It was football at its finest. It was Bernard Pollard making a great physical tackle, just as good a tackle as you're ever going to see in football right there. That probably turned the game around right there."
Patriots cornerback Aqib Talib hurt his thigh and defensive tackle Kyle Love injured his knee. Backup safety Patrick Chung was helped off the field after one play.
Record-setting tight end Rob Gronkowski, who broke his arm twice during the season, watched the game in owner Bob Kraft's suite. After the game, Kraft patted Brady on the helmet as he walked off the field.
"It always comes to a screeching halt," Brady said. "There's only two teams that advance. Those two teams deserve it. We've lost before. It takes a while to get over."
