There's a chance the Eagles will be without their top two quarterbacks when they open exhibition play against the Pittsburgh Steelers on Thursday night.

Nick Foles has been sidelined for three straight practices. He explained Tuesday there was enough discomfort in his neck for doctors to order “a couple of tests.” Foles had tendinitis in his right elbow last summer, and three years ago, suffered a season-ending fractured left collarbone.

“Muscle spasms, right here,” Foles said, touching the right side of his neck. “I know all you are wanting to go in every which direction. It’s going to be fine. Just being smart with it.” Though Foles thinks the spasms came out of nowhere, with Carson Wentz limited in practices, he may have gotten a few more snaps than planned.

"It's not a big deal," Foles said after Tuesday's session. "We're just being smart." Foles did not rule himself out for Thursday's game, calling the situation day-to-day. Head coach Doug Pederson said the soreness Foles has been experiencing is completely unrelated to the elbow injury that forced him to miss extended time last training camp.  Foles said he’s not completely sure how the injury happened, but mentioned that with quarterbacks, things sometimes get aggravated.  Nick Foles Jersey . It seems very unlikely the Eagles would force Foles into game action in a couple of days in the preseason opener, but Pederson and Foles didn’t rule it out. 

“We’re still talking about it. Day to day,” Foles said. “We’re worrying about the training room right now, we’re going through the rehab protocol. We’ll see. We never rule anything out. But at the end of the day, we’ll see what happens.”

While Foles hasn’t practiced at all the last three days, Carson Wentz has continued to participate in 7-on-7s, but not 11-on-11 drills. The team saw what they wanted from Wentz in full-team drills last week and doesn't want him to get inadvertently bumped.
