UPDATE: Steve Corkran reports that Keller’s signing is official. The Raiders waived QB Erik Meyer to make room for him.

Looks like the Raiders’ backup quarterback situation is going to get a bit more muddled, with word coming from a source close to Sam Keller that the ex-San Ramon Valley High, Arizona State and Nebraska signal-caller will sign with Oakland today.
Keller worked out with the Raiders at a post-draft mini-camp, but left without signing a contract. The Raiders later re-signed Marques Tuiasosopo, who joined Andrew Walter as the main competitors to back up JaMarcus Russell.
Keller would join Erik Meyer and Jeff Otis, giving the Raiders six quarterbacks heading into training camp in July. Our reporters thought Keller was actually more impressive than both Otis and Meyer in May.

We could soon be getting some answers in what happened to Raiders wide receiver Javon Walker in Las Vegas. Police there arrested a suspect today in the robbery and beating case.
According to the Associated Press, 30-year-old Arfat Fadel was arrested and charged with a bunch of felonies, including kidnapping and robbery. Apparently, Fadel was arrested by Vegas police last Friday. They are still looking for a second suspect.
