The Raiders have released quarterback Andrew Walter, according to a source. Walter, a third-round choice in 2005, was the odd man out with veterans Jeff Garcia, Bruce Gradkowski and Charlie Frye behind starter JaMarcus Russell. "I'm very excited for a fresh start," Walter said. "We'll see what happens. The only thing different that I would have hoped for is that it would have happened earlier. Things haven't changed since February and it occurred just now."
