Sam Williams, LB, Re-signed

The Raiders re-signed Sam Williams to a one-year contract Tuesday -- a move that prevents the veteran outside linebacker from hitting the free-agent market next month.

Williams, 27, was a third-round draft pick of the Raiders in 2003. He began last season as a starter but lost his job to Robert Thomas after a shoulder injury.

Also, strength and conditioning coach Jeff Fish accepted a job with Atlanta.

The Raiders did not issue a release on either move. Williams, who attended Clayton Valley High School and Fresno State, couldn't be reached for comment.

Bills: Buffalo signed free agent tight end Teyo Johnson. The four-year veteran out of Stanford has appeared in 30 NFL games and has 26 catches for 288 yards. He was in Denver's training camp in 2007, but after an injury late in the preseason, was waived by the Broncos. A second-round draft pick of the Raiders in 2003, Johnson has also spent time with Arizona and Miami.
