PHILADELPHIA (973espn.com) — The Eagles held their first and only "open practice" of the summer Sunday before 40,000 Sunday at Lincoln Financial Field, raising nearly $500,000 for the organization's Autism charity.

It was a nice respite from the players' perspective in what is the dog days of camp. The lower bowl of the stadium was full, providing a nice atmosphere to the usual monotony of practice.

"It gives us a nice lift during sort of the dog days of training camp," defensive coordinator Jim Schwartz said before practice. "Players get to come out here, particularly the young players that have never experienced it. See where their locker would be and go out there and just experience the crowd."

There are practical values as well to being at the Linc, according to Schwartz.

"It's even good to test your communication," he said. "Guys are used to being able to – we have music at practice but guys can talk over the music, but it's hard to talk over 40,000 [fans] or whatever we'll have today. I know they'll be loud. That's good for us, also."

What's not good is the second cart in two days.

Back on Saturday at the NovaCare Complex, linebacker Kamu Grugier-Hill suffered a Grade 3 MCL sprain and he entered Sunday might's practice on crutches. The sequel might even be worse, however, as defensive end Joe Ostman, like KGH, having a great camp, was carted off after suffering a leg injury during a special teams drills.

Many of Ostman's teammates, including Carson Wentz, consoled him before he was taken off, conveying a seriousness to the injury.

An undrafted rookie from last year, Ostman spent most of his rookie year on the Eagles’ practice squad where he was lauded for mimicking players like Aaron Donald, Khalil Mack and Cameron Jordan on the scout team.

Also, banged-up was receiver Shelton Gibson, who had to be helped off after suffering some got of left leg injury.

On the field, DeSean Jackson was the star, receiving a huge ovation in his return to LFF, before dusting Rasul Douglas in 1-on-1 drills and then coming back for an underthrown Wentz pass in team drills for a huge gain in front of Rodney McLeod.

Wentz also ignited the crowd by turning a negative -- a Malik Jackson batted pass at the line of scrimmage in the red zone -- into a positive, by snatching the football out of the air and running it into the end zone.

Defensively new safety Johnathan Cyprien came up on Josh Adams in 7-on-7 drills, delivering a hit and forcing a fumble although the scoreboard credited the former No. 41, Godwin Igwebuike, who was waived and claimed by the Jets earlier Sunday.

"We are going to plug him in in a lot of different places," Schwartz said of Cyprien. "We expect a lot from our safeties. We need multi-dimensional players; we think he is. We'll just see where it takes us."

PRACTICE NEWS AND NOTES:

-Grugier-Hill's injury was labeled as week-to-week by the Eagles and an MCL with his severity usually takes six to sight weeks. Casey Tucker, who has been the third-team right tackle, is out with a concussion after getting into a scrap with Shareef Miller on Saturday.

"A little banged up," KGH said after practice. "But, it’ll be a quick one; I’ll be back. ... It’s hard to put a time frame on it right now, but it’ll be definitely be early [in the season]."

-Corner Jeremiah McKinnon did a nice job against J.J. Arcega-Whiteside in the end zone on a fade pattern in 7-on-7 work.

-Joshua Perkins stood out with a nice one-handed TD catch from Nate Sudfeld in red-zone work.

-Sunday serves as Military Appreciation Day as well for the Eagles and the players gave their military-themed jerseys to members of the Armed Forces after the session.
