PHILADELPHIA -- Five key members of the Philadelphia Eagles missed practice Wednesday as the team began preparations for Sunday's Week 5 matchup with the Minnesota Vikings.

Defensive end Derek Barnett (shoulder), running back Corey Clement (quadricep), defensive tackle Fletcher Cox (ankle), wide receiver Alshon Jeffery (chest) and running back Darren Sproles (hamstring) did not practice, while left tackle Jason Peters (quadricep) was a limited participant in the session.

On the surface, that list is rather alarming, given that it features three starters and two of the team's top three running backs. But according to the Philadelphia Inquirer's Zach Berman, the absences of Cox and Jeffery are nothing to worry about.

"Hearing nothing to worry about with Alshon," Berman tweeted.

Jeffery said after the Tennessee Titans loss he had the wind knocked outof him after he made his first catch, a stumbling 31-yarder after which he fell hard and sat out a couple plays on the sideline. He caught eight passes for 105 yards and a touchdown against the Titans in his first game since offseason shoulder surgery.

Jeffery also missed time last week with an illness.

"Nothing to worry about with Fletcher Cox, either, from what I understand," Berman added.

Cox exited the Titans game briefly with an injury. He went down after a play and the training staff came out to look at him. He returned on the next drive.

Cox was in the locker room Wednesday, but he didn't speak to the media.

Sproles hasn't played or practiced since the Week 1 win over the Atlanta Falcons, and coach Doug Pederson didn't
