The Raiders are interested in veteran cornerbacks Mike Jenkins and Tracy Porter, according to several reports.

General manager Reggie McKenzie targeted defensive linemen and linebackers much of the first two weeks of free agency. Now, he has shifted his sights toward doing something about the dearth of talent at cornerback on his roster.

Jenkins played for the Dallas Cowboys his first five NFL seasons. Porter spent last season with the Denver Broncos after spending his first four NFL seasons with the New Orleans Saints.

As of now, the Raiders are without a proven starting cornerback on their roster. Ron Bartell and Shawntae Spencer started at cornerback in the opener last season, with Bartell released late in the season and Spencer's one-year contract expired.

Earlier this month, the Raiders checked into the prospect of signing veteran cornerback Terence Newman. As of last night, Newman said he still hasn't decided whether to re-sign with the Cincinnati Bengals or go with the Raiders.

Regardless, it's likely that the two players that start for the Raiders in the 2013 regular-season opener aren't even on the roster right now. Signing Jenkins or Porter could help solve that issue.

Also, this year's draft features more than a handful of highly regarded cornerbacks, so McKenzie could find additional help through that avenue.

Some mock drafts project the Raiders taking Alabama cornerback Dee Milliner with the third pick of the first round.
