Vontae Davis is not taking his free agency lightly. On Wednesday, Davis touched down in Oakland to meet with the Raiders, a source tells NFL.com’s Ian Rapoport (Twitter link).

This marks Davis’ fourth known free agent visit of the last week. In recent days, the veteran cornerback has met with the 49ers, Browns, and Bills. There could still be more meetings down the pike for the former first round pick.

The Raiders have a clear need in the secondary after releasing cornerback David Amerson.
