CHICAGO -- Although the Bears surrendered way too many yards on the ground to Eagles running back LeSean McCoy, the defense did force three turnovers and played a respectable second half.

"We had some little mistakes on those first two drives, but after that we settled down," Zack Bowman said. "We went out and got it corrected, and just went out and did our jobs."

Bowman, who picked off Donovan McNabb in the second quarter, has intercepted a pass in three consecutive games. Fellow cornerback Charles Tillman forced three fumbles, two of which were recovered by the Bears. The veteran has 21 forced fumbles in this NFL career -- the most by any defensive back since Tillman entered the NFL in 2003.

Corey Graham replaced Danieal Manning at the nickel position, as Manning played exclusively at free safety Sunday night.

Just promoted from the practice squad, running back Kahlil Bell made the most of his opportunities, rushing for 81-yards on only four attempts -- Bell's first NFL carry went for 72-yards.

"It was one of our standard zone plays," Bell said. "The offensive line did a great job of blocking, and Jason McKie did a good job of digging the guy out of the hole. It doesn't take much to be a good running back if you have holes like that."
