The Raiders reportedly worked out two wide receivers today-Tiquan Underwood and Jabar Gaffney. Pro Football Talk reported the Gaffney visit and Underwood confirmed his visit via Twitter. With the team's injury concerns at the moment, they are suddenly in a bit of desperation at the receiver position. Denarius Moore and Jacoby Ford are still not practicing full and Juron Criner now has an ankle injury he's nursing. That leaves the Raiders with just two healthy receivers in Darrius Heyward-Bey and rookie Rod Streater. Source: SBNation.com
