The Raiders likely are without their top two wideouts this week, with Michael Crabtree suspended and Amari Cooper recovering from an ankle sprain and a concussion.
In need of help at the position, the team will promote Isaac Whitney from the practice squad, via Michael Gehlken of the Las Vegas Review-Journal.
Whitney is expected to play.
Whitney, who caught 11 passes for 144 yards and two touchdowns in his two-year career at USC, signed with the Raiders as an undrafted free agent in May. Oakland waived him after the preseason and then signed him to its practice squad.
