"The Bears are at their best when they win the turnover battle, which might be a difficult task come Sunday.

The Eagles, thanks to a relentless, blitzing defense, are second in the league with a plus-10 turnover ratio, while the Bears check in at 26th with a minus-5.

Over the last two games, cornerback Zack Bowman has two interceptions. Bowman and fellow starting corner Charles Tillman, who has the team's lone defensive touchdown, will be counted on to make plays against Eagles quarterback Donovan McNabb and his receivers.

"They're fast guys," Bowman said, referring to receivers DeSean Jackson, Jeremy Maclin and Jason Avant. "They don't weigh that much, but they do have some fight in them."
