OAKLAND, Calif. -- Josh Cribbs made it clear after the loss to Oakland that he wants to re-focus on special teams because his role on offense is "very insignificant."

Cribbs had five passes thrown his way and caught two for 30 yards, including a 23-yarder on a TD drive in which he used a nifty spin move for extra yards.

"I'm very insignificant on offense, so I need to be out there heavily on all special teams," said Cribbs. "I got the ball only twice, so that's insignificant right there. Snaps, it's insignificant. I want to help my team win. You get the ball to your athletes. I feel like where I'm an asset on this team is special teams and I want to re-focus on what got me into this league."

Cribbs added, "I want to say stuff, but I don't want to be a problem. I'll play [more] special teams because I'm not getting the ball."

He said he wouldn't want to change things "if I was making more of an impact" on offense. Instead, he'd like to get back to covering kicks and punts. He said he felt helpless watching the Raiders' Jacoby Ford score on a 101-yard return.

"I make tackles on special teams," he said. "I led the team every year when I was on coverage and I'm a dynamic special teams player. I don't remember a touchdown being scored on us being out there. I feel like we have enough receivers on offense to get things done. My touches this game are insignificant to the value I can bring to special teams."

He said he'll see if the coaches will be willing to put him back on coverage. Cribbs was the No. 3 receiver this week as rookie Greg Little was elevated to a starting job. Little finished with a team-high six catches for 72 yards, and came a yard shy of his first TD.

"Greg has been going good, he's stepped up a lot," said Cribbs. "We have capable receivers. My two catches aren't significant enough."

He said he wasn't being critical of the coverage units.

"We have capable guys, they've been making plays all year," he said. "I just feel like I can help rally the guys to make it even more powerful. Those guys are great, but they're young. I can add some experience on there and help them create more plays."

He finished by saying, "I ain't got to ask. I'm a vet, I just do. I'm on [special] teams. Get somebody else out [as a receiver]."

Bell rung: Scott Fujita, who knocked Raiders QB Jason Campbell out of the game with a broken collarbone on a clean tackle, left with a concussion. He did not meet with the media after the game and will be re-evaluated Monday.

Center of action: Center Alex Mack started despite undergoing an appendectomy 13 days ago.

"I think his effort to come back was heroic," said Pat Shurmur.

Mack, part of a line that surrendered two sacks, acknowledged that playing so soon "was not the ideal situation for me." But he didn't want to let down his teammates.

"It was important to me and to the team to get out there and play," he said. "Luckily my health was in a state which we felt it was a good idea to do that."

He said he was rusty without practice and that "prepared better I'll play better." He also said he wouldn't recommend what he did.

"I wouldn't want anyone else that had surgery to rush too quick. It's not like we're setting the bar here on who can come back fastest."

Sitting out: Cornerback Joe Haden (sprained knee) said he had known for a while that he wasn't going to play Sunday. He was replaced by Dimitri Patterson, who gave up some plays but helped the defense hold the Raiders' offense to 10 points.

"It's just been getting better every day, but we don't really have a time frame on it yet." Haden said, declining to reveal the nature of the sprain.

"You always want to be out there with your boys helping them out," he said. "But it's just another step. You just know everybody else has got to step up, raise their level of play and just hopefully I'll be back out there soon."

Eager to help out: Terrelle Pryor said he's ready to step into the backup role now that Campbell is out for the year, according to an interview to the NFL Network.

"I don't want anyone to go down," the former OSU QB said. "I'm just here to work hard and make a lot of people proud in any way I can. Tomorrow I'm coming into work and doing the same thing I've been doing -- getting better. My confidence is never a problem. I'm a very confident guy."

Donovan misses game: Browns radio announcer Jim Donovan did not make the trip because he felt ill before the team left Cleveland on Friday afternoon.

It's the first game Donovan has missed since taking over as Voice of the Browns in 1999.

Donovan realized his goal of recovering from a bone marrow transplant in June to treat leukemia and returned to the microphone for the Browns' regular-season opener. It is not uncommon for recipients of the procedure to experience high fever throughout their recovery.
