Moore misses practice, Meriweather limited

LAKE FOREST, Ill. -- A sprained ankle kept starting nickel back D.J. Moore on the sidelines Wednesday as the Bears hit the practice field in advance of traveling to Oakland to face the Raiders.

Moore initially suffered the ankle injury a week ago on the practice field, which forced him to sit out the last game against San Diego. Corey Graham filled in for Moore at nickel, and recorded his second interception in the last two games. Graham also replaced Moore in the fourth quarter of the team's victory over Detroit in Week 10.

"[Corey] has done a great job," Bears head coach Lovie Smith said. " I think out of 19 plays or so in the last two weeks, he has two interceptions, so he's been pretty productive. He had a big tackle last week also. We really haven't missed an awful lot."

Graham would once again man the nickel spot if Moore isn't ready to return Sunday versus the Raiders.

Meanwhile, safety Brandon Meriweather was limited on Wednesday because of a concussion. Quarterback Jay Cutler is officially out for Sunday after undergoing what the organization called successful surgery to repair a broken right thumb.

For the Raiders, ten players skipped practice, including receiver Darrius Heyward-Bey (neck), running back Darren McFadden (foot) and defensive tackle Richard Seymour (knee).
