The Seattle Seahawks have signed Ryan Longwell.

Longwell didn't kick in 2012, but is a 15-year veteran.

Steven Hauschka has been placed on injured reserve with a strained calf.

The 49ers signed kicker Billy Cundiff on Tuesday to compete with struggling veteran David Akers, according to an ESPN.com report.

"He's thrilled with the opportunity to be in a position to help the team in any way he can this postseason," said Cundiff's agent, Paul Sheehy. "It's a great opportunity, with a great organization."
