On Monday afternoon, following the Eagles' season-opening win, head coach Doug Pederson addressed the injury status of starting cornerback Ronald Darby, who left Sunday's game with an ankle injury and did not return.

"This is something we're going to gather a little more information on this. Talking with our doctors and (director of sports medicine/head athletic trainer Chris) Peduzzi we need to get some more information on it before we make a full statement on it," Pederson said.

Pederson would not confirm an NFL Network report that indicated Darby would be out for 4-6 weeks.

Darby went down early in the second quarter when his right foot lodged into the turf at FedEx Field and was carted off the field moments later. Patrick Robinson took Darby's place on the outside. Third-round pick Rasul Douglas, who was inactive on Sunday, will be in the mix as well.

"We'll look at that this week too. We do have obviously Rasul sitting there and C.J. (Smith) but we'll look at it, talk with (defensive coordinator Jim) Schwartz the next couple days, and have a plan. If (Darby) can't go, then possibly Rasul."

Tackle Jason Peters left the game late in the second quarter with a groin injury. He returned to take one snap in the second half before returning to the sidelines. Peters is listed as day to day. The All-Pro tackle said after the game that he will play. Kicker Caleb Sturgis sustained a hip injury in Sunday's game and his status for this week is uncertain as well. Pederson said the team will work out kickers this week just in case.

Here's what else Pederson shared on Monday:

On what he's seen from Rasul Douglas:

"He's put himself in a good position. I thought he came out of camp better. He improved from OTAs into Training Camp. He improved so I've got a lot of confidence in him if that's the direction we go on defense."

On the decision to throw deep early and often:

"It just goes without saying. You've got to take those opportunities. You've got to take those shots. You just see sometimes when maybe you're struggling offensively or maybe you're not moving the ball, something like that, the run game's not really clicking, defenses begin to kind of crowd the box and you start seeing more eight and nine guys sometimes around the box. We've got to continue to take shots and do that and we had them. We had them there yesterday. We got in behind the defense a little bit and just missed. By doing that it just shows, No. 1 you can do that offensively and, No. 2, it backs them up a little bit more and opens things up underneath."

On the production from the run game:

"Obviously at the end of the day, it's not good enough. We pride ourselves on running the football here and we've got backs and linemen and tight ends really that can help us do that. Watching the film last night on the way home and then again this morning a couple times, we're close. We just have to finish blocks and sustain blocks. There were a couple. This always happens going into Week 1. There's always a few unscouted defensive looks that they present that gave us some problems early. (We) made the corrections during the game and had some success later in the game on some of the same runs. It's close. We have to keep detailing it, keep working it, and continue to get better."

On whether it will be more difficult to play aggressive defensively against opposing receivers like Kansas City's Tyreek Hill and the Giants' Odell Beckham Jr. given Darby's injury:

"Those guys are always going to give you problems. They're tough to defend. You know speed guys, shifty guys. As we look at it, if Rasul's in there, if Jalen's (Mills) in there, (Jaylen) Watkins is in there, try to keep Patrick Robinson possibly at the nickel spot as much as we can. I think it's beneficial for guys to learn one spot and he's been comfortable in there. Can he get you out of a game at corner? Yes, he can. He did it yesterday a little bit.

"Then with the three safeties that we have, obviously we know Malcolm (Jenkins) can play nickel and Corey Graham comes in the game. It's going to be one of those situations where it takes all hands on deck these next few weeks to get the job done."

On coaching against former mentor Andy Reid in Week 2:

"It'll be fun to see Big Red on the other side but at the same time, I know he wants to kick my tail and I want to kick his. Andy Reid's teams are well-prepared as we know and we've got to do the same thing this week. We just have to be ultra-prepared. That's a tough place to play now. That's a loud, loud place and we've got to be able to handle that crowd noise. We've got to do it through communication, through nonverbal communication, all of that's got to be on point this week in practice. It'll be fun to get out there, but once we tee it up and kick it off it's all about the business. It's all about the game."
