Minnesota Vikings safety Harrison Smith was downgraded and is now listed as out for the Atlanta Falcons game because of a knee injury.

Smith was listed as questionable on Friday, but the team said on Saturday that he will be scratched. Smith was injured last week against Green Bay.

He missed the first two practices of the week, but was able to do some work on Friday, giving the Vikings (7-3) some hope that he could be ready to face the Falcons in Atlanta.

Smith leads the Vikings with 54 tackles this season.

Rookie cornerback Trae Waynes was also downgraded to out after being listed as questionable on Friday.

A win on Sunday would put the Vikings in first place in the NFC North by one game over Green Bay.

Titans add linebacker

The Tennessee Titans signed outside linebacker Yannik Cudjoe-Virgil from their practice squad and waived wide receiver Rico Richardson.

The team announced the moves Saturday.

Cudjoe-Virgil joined the Titans in the spring as an undrafted free agent out of Maryland. He was injured in the Titans’ first preseason game and placed on injured reserve, with the player and team reaching an injury settlement. The Titans re-signed him to the practice squad two weeks ago.

The addition of Cudjoe-Virgil adds some depth to the Titans’ front seven as they deal with outside linebacker Derrick Morgan’s injury.

History for Big Ben

Ben Roethlisberger figures he always will like Seattle a lot more than the city likes him.

The Pittsburgh Steelers quarterback said he has been to Seattle “two or three times. ... I’m a big outdoorsman, so obviously great fishing up there, and just visiting.”

What Roethlisberger, who ranks 13th all-time in passing in NFL history, has never done in Seattle is play a football game.

In fact, CenturyLink Field is the only current stadium in which Roethlisberger has not played — he was drafted in 2004 and Pittsburgh most recently played in Seattle in 2003.

There was a time Roethlisberger might have been viewed as public enemy No. 1 among Seahawks fans for his role in one of the most frustrating games in Seattle history — a 21-10 loss to the Steelers in Super Bowl XL.

That most frustrating “honor” now goes to last season’s Super Bowl loss to the Patriots.
