Seahawks fans rocked the stadium so hard during Monday night's matchup with New Orleans that seismic instruments registered tremors at various points in the game.

A magnitude 1 or 2 quake was recorded during Michael Bennett's 22-yard fumble return for a touchdown in the first quarter. The game, a 34-7 victory that clinched a playoff berth for the Seahawks, registered on nearby seismic instruments several other times.

Pacific Northwest Seismic Network director John Vidale said a small quake wasn't all that surprising in the stadium, which is built on pilings dug through soft ground in earthquake country.

Browns add QB

Battered and bruised at quarterback, the Browns have gotten a little healthier. With Brandon Weeden and Jason Campbell recovering from concussions, Cleveland signed quarterback Caleb Hanie, giving coach Rob Chudzinski another option this week at New England. Hanie spent four years backing up Jay Cutler in Chicago and was third on Denver's depth chart last season behind Peyton Manning and Brock Osweiler. The 28-year-old went 0-4 for the Bears in 2011.

Ex-Chiefs file suit

Five former Kansas City Chiefs players who were on the team between 1987 and 1993 filed a lawsuit claiming the team hid and even lied about the risks of head injuries.

The lawsuit was filed on behalf of former players Leonard Griffin, Chris Martin, Joe Phillips, Alexander Louis Cooper, and Kevin Porter. All five have opted out of a multimillion-dollar settlement with the NFL.

Plaintiffs' attorney Ken McClain called the proposed $765 million settlement between the NFL and ex-players insignificant and said it provides compensation only to the former players with the most severe brain injuries. None of the five plaintiffs will get money under that deal, he said.

"It's really a very small amount of money if you do the math. It's paid out over 20 years, it's $765 million total. . . . It's not very much money."

Lion will sleep Sunday

Detroit Lions linebacker Travis Lewis was suspended for the final four games of the regular season for violating the NFL's policy on performance-enhancing substances. His contributions have been mostly on special teams.
