The Oakland Raiders and free-agent cornerback Mike Jenkins have agreed to a one-year contract, a league source told ESPN NFL Insider Adam Schefter.

Jenkins, who spent the past six years with the Dallas Cowboys, is the second cornerback the Raiders have signed this offseason, having added Tracy Porter last week.

A former Pro Bowler, Jenkins lost his starting job last season when the Cowboys signed Brandon Carr to a five-year, $50.1 million deal and moved up in the draft to select Morris Claiborne.

"Jenkins is very capable, I think a good cornerback," Cowboys owner Jerry Jones said in March. "We happen to be pretty committed relative to the rest of our roster. We have to be pretty committed at cornerback. Under a different circumstances, Jenkins might be a little different story for us right now. He would be a different story right now, he certainly wouldn't be out of our radar as far as having him of bringing him back as a starter. I think Jenkins is a starting cornerback in the NFL."
