ALAMEDA –- The Raiders could be light on cornerbacks heading into a game where healthy bodies are at a premium.
The Denver Broncos run a track meet orchestrated by quarterback Peyton Manning, who has speedy weapons all over the field.
Carlos Rogers (knee), Chimdi Chekwa (hamstring) and TJ Carrie (ankle) missed Wednesday’s practice, and only Carrie seems certain to play.
That keeps the reserves low, with Nieko Thorpe left to support Tarell Brown, Carrie and the recently reactivated DJ Hayden.
“To play against the team we’re playing, make no mistake about it, your defensive backs need to be out on the field,” interim head coach Tony Sparano said. “This quarterback through eight incompletions against us in two games last year. Eight total incompletions, out of 65 attempts. That’s 87.3 percent completions. If you’re not out there and you’re not seeing it well, it’s going to be hard to play.”
Some other injury notes from Raiders practice:
-- Left guard Gabe Jackson was out with a knee injury. Per his custom, Sparano didn’t get any injury specifics, though he said “I don’t know if I would classify it as serious.”
-- Receiver Vincent Brown was a full participant for the first time in weeks. He’s missed time with a hamstring strain.
-- Fullback Marcel Reece was a full participant after being limited over the past three weeks with a quadriceps strain.
-- Cornerback Keith McGill returned to practice, though he remains limited with a groin strain.
