PHILADELPHIA (973espn.com) - Nick Foles is starting Sunday in Chicago.

How healthy the veteran quarterback will be against one of the best pass rushes in football is another matter, though.

“A little bit of soreness,” Foles said on Wednesday when asked about the bruised ribs that knocked him out of last Sunday's game against Washington, “but every day drastically improving.”

The issue actually dates back to the week prior when Houston's Jadeveon Clowney walloped Foles late in what turned out to be a comeback win over the Texans and sore ribs are not the first thing you want to be dealing with when Khalil Mack and Akiem Hicks are next on the docket.

As they have been doing for the previous two weeks the Eagles held a walkthrough practice on Wednesday and will not have a full on-field practice until Thursday, all in an attempt to keep the banged-up players like Foles as fresh as possible for game day.

Foles may wear a little extra padding to protect his midsection a little bit but other than that it's business as usual.

"I’ll wear my normal stuff, maybe add a little bit in there just for a little bit more, but other than that I want to be able to function and move around,” he explained.

The Clowney hit cost Foles one snap against the Texans and Philadelphia was cruising when Ryan Kerrigan smacked Foles last weekend, enabling the Eagles to finish up with Nate Sudfeld.

This Sunday, Foles understands Vic Fangio and the Chicago defense will know he's been having some issues but there can be no consternation when it comes to the injury.

“Just play fast, trust the guys up front,” Foles explained. “I can’t worry about [the ribs] when I’m playing. I’m going to drop back and play the game. We’re going to go out there and give it every single thing we have, so something I can’t worry about."
