The Raiders are hosting former Vikings safety George Iloka on a visit, as Ian Rapoport of NFL.com tweets. Former Giants safety Curtis Riley is also en route to Oakland, Michael Gehlken of the Review-Journal (on Twitter) hears.

The Raiders already invested heavily in the secondary by signing safety Lamarcus Joyner to a four-year, $42MM deal, but they’re expected to deploy him mostly at nickel corner. That leaves a serious need at safety, and Iloka and/or Riley could help fill the gap.

Iloka, a former Bengal, has history with defensive coordinator Paul Guenther, and that same connection led to a deal between the Raiders and linebacker Vontaze Burfictearlier this week.
