It's Time for Eagles Fans to Worry About Fletcher Cox

Philadelphia Eagles' defensive tackle Fletcher Cox is one of the best defenders in the game. He's a four-time Pro Bowler and consistently dominates the line of scrimmage for the Birds. His level of play is not what fans should be concerned about.
Eagles' fans should be worried about Cox's foot, which has kept him out of practice for most of the summer.
Doug Pederson said today he's still planning on Fletcher Cox and Nigel Bradham for Week 1. Hoping that they ramp up their activity this week. Bradham has taken part in some 7v7s, but not team drills. Cox still hasn't done anything other than individuals yet.

Cox injured his foot in the Eagles' playoff loss to the New Orleans Saints, forcing him to have surgery early in the offseason. Fast forward to now, and Cox has yet to participate in team drills at practice.
More recently, after participating in individual drills earlier this summer during OTAs, Cox is now rehabbing inside the practice facility away from the team and the media. Cox was not seen last week during practice, causing some media members to question the full extent of his injury.
Cox has maintained all summer he'll be ready for Week 1, but just last season cornerback Jalen Mills injured his foot in Week 8 against the Jacksonville Jaguars. He was originally listed as day-to-day, but was eventually placed on IR.
Eagles placed CB Jalen Mills on Injured Reserve and promoted DT Bruce Hector to active roster.

Mills has yet to return to the field, starting the summer on the PUP list. It's looking likely he'll miss the first six weeks of the season, which leads us to question what's going on with Cox.
If the All-Pro still isn't practicing by the start of next week, he's readiness for Week 1 should be widely discussed.
