SEATTLE— Some of the loudest NFL fans in the nation are trying to become the loudest in the world.

This Sunday, Seattle Seahawks fans will attempt to break the Guinness World Records mark for “loudest crowd roar at a sports stadium,” which was set in 2011 in Turkey at the Ali Sami Yen Sport Complex Turk Telekom Arena during a soccer match between Galatasaray SC and Fenerbahce.

The record is 131.76 decibels.

“Seahawk fans are always loud, so basically we’re going to measure it,” said Joe Tafoya, a former Arizona Wildcat and NFL defensive end who played one season for Seattle.

Tafoya now co-runs Volume 12, the fan group organizing the attempt. The group is footing the bill for the Guinness World Records official to come to Seattle. They’ve also found a sound engineer with equipment to do the measuring.

Seahawks fans are already known to be noisy, but on Sunday the game will be against the division rival San Francisco 49ers, the reigning NFC champs, and the stakes are already high for an early season game. The game is a sell-out.

The attempt at the roar record is not affiliated with the team. There won’t be an announcement, like what happened in Turkey. Instead, Tafoya hopes to get the word out through the fans.

While the noise will be recorded through the game, Tafoya wants the fans to cheer the loudest when the 49ers take their first possession.

“Hopefully, we’ll be able to break the record then so I’ll be able to sit back and watch the game,” he said.

As a former player, Tafoya remembers well how loud CenturyLink stadium can get.

“I’ve played in about every NFL stadium. I played for the Cardinals, the Bears, I had a chance to travel, CenturyLink was by far and away the loudest,” Tafoya said. “The noise, it almost seems like it turns into energy.”

Freeman misses photo

TAMPA, Fla. — Tampa Bay quarterback Josh Freeman recently missed a meeting for a team photo, but says it was an isolated incident that hasn’t been a distraction for the team.

The fifth-year pro said he overslept and did not show up on time for an early morning photo shoot on Labor Day. Later, he was not selected as a team captain, but doesn’t feel the vote was related to the absence.

Instead, receiver Vincent Jackson and guard Davin Joseph were voted offensive captains in a vote of players.

“We’ve got a team with eight Pro Bowl guys,” Freeman said. “Do I want to be a captain? Sure. But it’s not something that’s going to make or break me by any stretch.”

PK in damage control

ALAMEDA, Calif. — Oakland Raiders place-kicker Sebastian Janikowski has kicked off the infield dirt at the Coliseum for so long now that it’s become almost second nature to him.

That’s why Janikowski was surprised — and angry — to read a published report quoting Jacksonville kicker Josh Scobee, claiming Janikowski annually roots for the Oakland Athletics to miss the playoffs so the dirt can be replaced with sod.

“I root for the A’s, I want them to do well,” Janikowski said Thursday. “I’ve been to several A’s games. Whatever (Scobee) said, it just blows my mind. The conversation never happened.”

Browns RB: Feed me

BEREA, Ohio — Cleveland running back Trent Richardson sent his message loud and clear Thursday — he wants the ball more when the Browns (0-1) visit Baltimore (0-1) for an AFC North game.

Richardson had 13 carries for 47 yards (3.6 average) to go along with two catches for 30 yards Sunday in the Browns’ 23-10, season-opening loss to Miami.

“I don’t think (the Dolphins) really stopped the running game,” Richardson said. “I think we stopped it ourselves as far as just getting away from (it). We were behind and stuff.”

In the five games in which Richardson had 20 carries or more, he averaged 95.8 rushing yards per game, and the Browns went 3-2. In the 11 games in which he received fewer than 20 carries, including Sunday, he averaged 47.1 yards per game, and the Browns went 2-9.

Extra points

• Chargers rookie linebcker Manti Te’o isn’t expected to be ready for Sunday’s game, but defensive end Sean Lissemore (elbow) is expected to play. Te’o hasn’t practiced since spraining his right foot Aug. 8, but he no longer wears a walking boot on his right foot and is making cuts.

• The New Orleans Saints have signed defensive end Jay Richardson, bolstering their defensive line following a left knee injury to end Tyrunn Walker in Week 1. The club also waived receiver Andy Tanner.

• The New York Giants were awarded linebacker Allen Bradford off waivers and placed linebacker Dan Connor on injured reserve with a neck problem. Bradford was released by Seattle on Wednesday.

• Jacksonville could be without both starting cornerbacks against Oakland. Veteran Alan Ball left practice Thursday after injuring his groin. Fellow starter Dwayne Gratz (ankle) already has been ruled out.
