PHILADELPHIA -- Eagles cornerback Ronald Darby is "on schedule" in his recovery from a dislocated ankle, per head coach Doug Pederson, with the team eyeing Week 7 as a potential return date.

Pederson made it clear, though, that this remains a fluid situation.

"He's getting there, obviously," said Pederson. "We'll continue with the rehab this week and get him moving a little bit more. He's on schedule. But with the severity of the injury, as you saw in the Washington game, it's just going to take time."

Darby suffered a gruesome-looking injury in the opener against the Washington Redskins, his ankle bending unnaturally as he planted while in coverage. As he was being carted off, it seemed like a very real possibility that he'd be lost for the season. But following an MRI, it was determined that he would not need surgery and a four-to-six week timetable was set for recovery. Pederson indicated that the team is hoping he'll be back once they get past the six-game mark. If that proves to be the case, it would set up a Week 7 return for Monday Night Football against the Redskins -- the same team he suffered the injury against.

"That's kind of the target deadline, if there is one," said Pederson. "But I'm not going to hold it as a hard deadline. I'm not going to put him in a box. These things take time. You saw the replay and you saw the ankle; it just takes time."

Meanwhile, rookie corner Sidney Jones (Achilles rupture) is progressing but there is no timetable for him, said Pederson. He is currently on the non-football injury list and is not eligible to play until after Week 6.

As for this week's matchup against the Arizona Cardinals: Defensive tackle Fletcher Cox remains "day-to-day" with a calf injury that forced him to miss Sunday's game at the Los Angeles Chargers. He will not practice Wednesday.

The Eagles could be getting some of their secondary depth back this week with safety Corey Graham and cornerback Jaylen Watkins returning to practice on a limited basis after missing time with hamstring injuries.
