David Garrard has a herniated disk and is going to schedule back surgery this week. The Raiders had reached out to the free-agent quarterback in the wake of Jason Campbell's broken collarbone, but Garrard informed the team that he is not available. "The Raiders were in contact with my agent, Al Irby, last night and he was straight with them about my back problem, that I also was having a second opinion today. So it's disappointing because I wanted to play but my doctor says this surgery won't prevent me from playing next year," Garrard said. Garrard said he has "lost a lot of feeling in my lower left leg and even my left foot has gone dead on me."
