The Oakland Raiders have signed Spencer to a one-year deal in their latest move to bolster their depleted secondary.||||||| Spencer's agent, Peter Schaffer, says Spencer thought the Raiders were the best fit for him and he is excited to make the move across the bay after playing his first eight NFL seasons with the San Francisco 49ers. Spencer started 72 games his first seven years, including all 32 in 2009-10. But he lost his job in training camp last year and spent most of his final season with the 49ers as a reserve.

Shawntae Spencer became the odd man out in San Francisco's secondary. The 49ers released the cornerback Thursday after he spent eight seasons with the team. The 30-year-old Spencer started every game in 2009 and 2010 but appeared in only nine games with no starts for coach Jim Harbaugh and the NFC West champions last season.||||||| On Tuesday, the 49ers signed cornerback Perrish Cox. They also have agreed on a new $31.3 million, four-year contract with Pro Bowl cornerback Carlos Rogers. San Francisco selected Spencer in the second round of the 2004 draft, out of Pittsburgh. He has 345 career tackles, 11 interceptions, three forced fumbles and a touchdown in eight NFL seasons.

Spencer will miss the rest of the season with a torn ligament in his left knee.||||||| Spencer, a fifth-year pro, will be placed on injured reserve soon after undergoing surgery Wednesday to repair the ligament. He injured his knee late in the 49ers' road victory at Seattle on Sept. 14, and missed last week's victory over Detroit. Spencer started 39 games in his first three seasons, but has been the 49ers' No. 3 cornerback since last year behind starters Walt Harris and Nate Clements. Tarell Brown and Donald Strickland will compete to replace Spencer.

Spencer is expected to miss Sunday's game against after getting injured last week.||||||| Spencer has a knee problem, but 49ers coach Mike Nolan wouldn't say who will replace him as the third cornerback.
