"They were blitzing us a bunch," offensive guard Marshal Yanda said. "They were getting in there more than we want them to."
Browns wide receiver Greg Little was involved in a few skirmishes with Ravens strong safety James Ihedigbo.
When Ihedigbo's helmet came off during a shoving match in the first quarter, Little launched it airborne several yards toward the sidelines and was flagged for unsportsmanlike conduct.
After catching a 15-yard pass and running out of bounds in the second quarter, Little shoved Ihedigbo and then gestured with his hand to try to encourage the defensive back to mix it up again, earning Little his second 15-yard penalty. The flag was quickly thrown and there wasn't a second fight.
"He was trying to be a tough guy," Ihedigbo said. "Some guys that aren't tough try to prove that they're tough. It's all good. I wasn't worried about that."
Campbell briefly left the game with a rib injury, but returned and finished with three touchdown passes. After the game, Campbell said he had no problem with Ngata, who apologized to him.
The Ravens took issue with the penalty considering there appeared to be no malicious intent from Ngata, who was airborne when Campbell was falling to the ground.
"Haloti is trying to make a tackle," Harbaugh said. "Haloti is in the air while Jason Campbell is in the air. Jason's running and because he ends up landing on him it's hard for me to understand why that's called. It's a judgment call."
Middle linebacker Daryl Smith was flagged for unnecessary roughness in the third quarter for slamming Little to the ground on an incomplete pass where he didn't have the ball.
"I don't think he thought he didn't have the ball," Harbaugh said. "He's trying to make a tackle. That's a big man, and it's tough to get him to the ground. I can't fault the two players on those penalties."
Shipley appeared to hold his own for the most part blocking defensive lineman Desmond Bryant, who finished with two tackles and no sacks. Shipley was flagged for one false start.
"I felt pretty good," said Shipley, who had previously made five starts at center. "I'm sure there will be some mistakes. It was a good front seven. I felt pretty good, but it's never good enough when you don't win."
After a heated confrontation in September where Browns nose tackle Phil Taylor smacked Rice in the head and accused him of spitting on him, there was no altercation this time.
“After the game, he came up to me and shook my hand,” Taylor said. “It was good.”
