Eagles defensive coordinator Jim Schwartz said his young cornerbacks need to be more consistent, coming off Sunday's 26-24 victory at the Los Angeles Chargers and looking at this week's matchup with Larry Fitzgerald and the Arizona Cardinals.

Schwartz noted Tuesday that big plays were again a problem for the Eagles against the Chargers, starting with the 75-yard reception that third-round rookie Rasul Douglas gave up to Tyrell Williams, which turned a 13-0 Eagles lead and a possible blowout into 13-7 and a struggle.

Schwartz acknowledged that Douglas "gave up a couple of plays."

"He's a competitor; he's a lot like Jalen [Mills, the other starter] in that way. … Last week [against the Giants], Jalen had given up a couple of plays, and when it came time to get a stop, he made two big plays to help get us stops. You have to play that way when you're a corner," Schwartz said.

"We need to play more consistently at the corner position. It's not just about a singular flash play. It's about consistency over the course of the game. Those guys are still working their way through that."

Schwartz said the Williams TD "changed the momentum of the game."

He praised veteran nickel corner Patrick Robinson for "good, consistent play."

Schwartz had no injury updates, so we don't know how close Douglas and Mills might be to receiving help from starter Ron Darby, sidelined since the opener with a dislocated ankle, or from the forgotten man of the Eagles' secondary, second-round rookie Sidney Jones.

Jones, a top talent who was available in the second round because he tore an Achilles while getting ready for the draft, can start practicing in Week 7. In fact, Monday morning, he tweeted the number 7, with three exclamation points. We're also coming up on the seven-month mark since his injury, suffered March 11. It's possible, of course, that Jones won't be ready to practice that quickly, but that there is some other recovery milestone associated with Week 7. Or it could just be a really delayed, cryptic reaction to the Carmelo Anthony trade.

"They've been very engaged in meetings. They've made use of their time, even though they've been on the shelf," Schwartz said. "When it comes time for those guys to get back on the field, whenever that is, they've both put themselves in good position to be ready when their body is capable."
