PHILADELPHIA -- The Eagles returned to the practice fields within the NovaCare Complex on Monday following a day of rest. For the second consecutive session, the team donned full pads for training camp practice.

Here are six takeaways and a handful of quick observations from the Eagles’ fourth training camp practice:

1. New absences at camp

While safety Blake Countess (N/A) returned to the field for individual drills, his spot on the sideline was filled by linebacker Paul Worrilow (ACL). Countess had missed the previous two sessions with an undisclosed injury. Worrilow was a full participant in practice during the first week of training camp.

Joining Worrilow on the sideline was wide receiver Mack Hollins. Following practice, Eagles coach Doug Pederson said that Hollins had suffered a new lower-body injury, indicating that it was not related to the groin injury that kept him out of action for all of last season. Hollins stayed in the locker room for the majority of practice but eventually emerged in street clothes.

Cornerbacks Jalen Mills (foot, PUP) and Cre’Von LeBlanc (foot) remained out of action. Following practice, Pederson said LeBlanc was dealing with a week-to-week injury.

2. Solid debut for Scandrick

Newly signed cornerback Orlando Scandrick played the nickel spot for the second-team defense on Monday. He was signed on Saturday following the team’s third practice session. The Eagles threw him right into the fire and he responded well.

During 11-on-11 drills, Scandrick made a nice play in coverage. Backup quarterback Nate Sudfeld targeted wide receiver Greg Ward Jr. (more on him later) on a crossing route and Scandrick got in front of the pass-catcher to bat down the ball. Scandrick’s leaping pass breakup was a good sign for the veteran, who remained on the market for quite some time. Following practice, he said part of the reason he signed with the Eagles was because of his relationship with lifelong friend and former rival, DeSean Jackson.

Scandrick is wearing No. 45 at practice.

3. Deep-reserve wide receivers step up

A week of work can make a big difference. After failing to stick out during the first three practices, wide receivers Braxton Miller and DeAndre Thompkins made multiple plays with the depth units. Miller’s highlight came on a sideline grab off a pass from quarterback Cody Kessler. Thompkins made a really impressive diving catch with the first-team offense, as quarterback Carson Wentz targeted him down the field.

Along with the emergence of Thompkins and Miller, Greg Ward Jr. continued to make plays. He made a nice diving catch during 11-on-11 drills. He was in tight coverage and sold out for the ball. He is having a strong camp.

Former Rutgers wide receiver Carlton Agudosi made a pair of notable catches in team drills as well. The 6-foot-6 wide receiver will be a player to watch in the preseason. He may be hard to sneak onto a practice squad.

4. Physicality creates some drama

On several occasions, the padded practice felt a bit more intense than previous sessions. In particular, during 11-on-11 drills, running back Boston Scott ran over safety Trae Elston. The running back was able to stay on his feet and break away for a big run.

Early on during practice, defensive tackle Timmy Jernigan launched himself into the backfield and took down running back Jordan Howard for a massive loss of yards. Jernigan has looked very quick off the line during camp so far.

The physicality wasn’t limited to just hits. Howard made an impressive blitz pickup during 11-on-11 drills and the block allowed Wentz to target wide receiver DeSean Jackson on a “go” route. A few plays prior, tight end Zach Ertz made an impressive lead block to open up space for running back Darren Sproles. The veteran running back picked up at least 20 yards on the play.

5. Wentz-to-Jackson is automatic

It’s becoming evident that the chemistry between Wentz and Jackson will cause problems from the rest of the NFC East. The two have been playing catch during 11-on-11 drills. Jackson has beat nearly every cornerback in coverage multiple times and gotten open in several different ways. Jackson isn’t just winning with speed, he’s also getting space with his route-running ability.

On Monday, Wentz continued to make bucket throws to Jackson. As previously mentioned, the pair connected on a downfield shot for a touchdown. The play picked up at least 50 yards. Wentz also hit Jackson on comeback routes and sideline fades. They are clicking like they’ve been together for years.

6. Defense makes some plays

Linebacker Kamu Grugier-Hill was awarded a sack on Wentz during 11-on-11 drills. The quarterback threw the ball after the whistle and it was picked off by safety Malcolm Jenkins.

Safety Tre Sullivan, who had a nice overall practice, started second-team reps with a sack on Sudfeld. Sullivan was sent on a blitz and immediately got home. He had a pass breakup later in the day as well.

Cornerback Rasul Douglas picked off Wentz during 3-on-3 coverage drills. Douglas drew wide receiver Alshon Jeffery in one-on-one coverage and Douglas was able to come down with the ball off the contested catch. Douglas is having a very strong camp. In fact, one could argue he has been the best cornerback in camp thus far.

Former Rutgers defensive tackle Kevin Wilkins, who has shown signs of progress lately, produced a “sack” on Kessler during 11-on-11 drills.

Quick Hits:

- Following practice, Wilkins carried pads for the starting defensive line. Wilkins carried the pads for Fletcher Cox, Vinny Curry, Brandon Graham and Malik Jackson. The rest of the rookies fetched Rita’s icee cups for the veteran players.

- The battle for the No. 3 quarterback job seems a lot more wide open than most spectators previously thought. Kessler and rookie Clayton Thorson are getting relatively even reps at quarterback. Kessler has looked better than Thorson by a large margin. However, it’s worth noting that Kessler is taking part in his fourth training camp and he has more playing experience than Sudfeld, who is expected to be Wentz’s backup.

That said, Thorson has made some really bad throws so far. He had one pass that sailed out of bounds, roughly 10 yards away from his target on Monday. Thorson, like any draft pick, deserves time to get acclimated but the early results have been pretty rough.

- Backup center Stefen Wisniewski had a pretty strong practice after a week of miscues. His snaps were clean -- from what I saw -- and he did a good job of anchoring in protection.

- Scouts from the CFL’s Toronto Argonauts and Winnipeg Blue Bombers attended practice. The scouts are looking for bottom-of-the-roster prospects.
