Koch didn't care if the Raiders were upset, enjoying the moment.
"Oh, not that I know of," Koch said when asked if the Raiders reacted angrily. "I was too busy doing high-fives and spiking the ball."
Pro Bowl running back Ray Rice gave the punter high marks for his running style.
"It was better than mine," said Rice, who scored on a 7-yard touchdown run earlier. "He set up his blocks. I'm going to have to take a few lessons out of his book."
J. Jones sets return record
For the second time this season, kick returner Jacoby Jones dashed into the record books.
After tying the NFL record for longest kickoff return with a 108-yard return against the Cowboys, Jones scooted 105 yards on a kickoff in the fourth quarter Sunday.
Jones is the first Raven to have more than one kickoff return for a touchdown in the same season. He's the only player in NFL history to have two kickoff returns of at least 105 yards and the ninth to ever have two kickoff returns of 100 yards or more.
"They brought me in to play my role, and I'm going to do whatever I have to do to succeed," said Jones, who's averaging 38.6 yards per kickoff return after being signed to a two-year, $7 million contract in the spring. "Every time they call my name, I'm going to try to make a play."
Jones still had enough energy in the end zone to celebrate with a dance.
"That's old-school, man," Jones said. "It's called 'Cabbage Patch.'"
Reid replaces Williams
Williams only practiced once last week and was listed as questionable.
"What Jah needs is playing time," Harbaugh said. "He needs experience. It was our plan to start him out there in the third series no matter what and then play him as much as we could. He played well."
A 2011 third-round draft pick, Reid was inactive for the first seven games due to a strained right calf.
Reid threw a solid block on Rice's 7-yard touchdown run.
"It was awesome to be a part of it," Reid said. "Of course, I had some growing pains. I've got to learn from my mistakes. I definitely need a lot of improvement.
"I seemed to be doing all right, so they left me in there. The more playing time I get, the happier I am."
Williams downplayed the severity of his injury.
