The Raiders continued to rebuild their defensive secondary Tuesday, announcing the signings of Mike Jenkins and Usama Young.
Jenkins is the second presumptive starter at cornerback the Raiders have signed in the last two weeks.
The Raiders also signed defensive end Andre Carter, who played 12 games in Oakland last season.
Last week, veteran Tracy Porter was signed to position that until then included only Phillip Adams, Brandian Ross and Chimdi Chekwa.
It's the second time in two seasons Raiders general manager Reggie McKenzie signed second-tier free agents who figured to be immediate starters. ESPN reported Jenkins agreed to terms with Oakland Monday.
Last season, Oakland signed Ron Bartell and Shawntae Spencer, who ended up as Week 1 starters. Neither worked out, as Bartell broke his shoulder blade in the opener, missing several weeks before returning to the roster and then eventually being released, and Spencer sustained a severe mid-foot strain in Week 2 that ended his season.
Jenkins is a veteran of 71 games and 48 starts for the Dallas Cowboys. He was a Pro Bowl performer in 2009, a year after being a first-round selection out of South Florida in 2008.
Last season, Jenkins played in 13 games with two starts as his role was diminished after Dallas signed free agent Brandon Carr and drafted Morris Claiborne in the first round.
Young, a seven-year veteran, played the last two seasons with the Cleveland Browns, starting 11 games last season with a career-high three interceptions and 1.5 sacks. He was originally a third-round pick of the New Orleans Saints, where he played four seasons and was coached by Raiders coach Dennis Allen.
With Matt Giordano an unrestricted free agent and Michael Huff having been released and signed with the Baltimore Ravens, Young becomes the prime candidate to start at free safety.
Carter, 34, played in 12 games for the Raiders last season with 2.5 sacks, still showing good pass rushing skills on occasion after recovering from a torn quadriceps muscle at the end of the 2011 season while a member of the New England Patriots.
He is the second of the Raiders' 17 unrestricted free agents to rejoin the team, along with right tackle Khalif Barnes.
