Now that Riley Cooper is sidelined with a fractured collarbone, will rookie wide receiver Marvin McNutt get a shot to earn some more playing time? And will the Eagles take a look at Plaxico Burress? Answering those questions and more right here.

Each morning during training camp, we’ll be bringing you the Eagles wake-up call with links and notes from Lehigh. Today, we address Plaxico mania, and visit some ghosts of Eagles past and present.

For first-round pick Fletcher Cox, this was just part of the learning process.

With the Eagles in full pads for the first time this summer, Cox participated in one-on-one drills against the offensive linemen. On one rep, last year’s first-round pick, Danny Watkins, stood his ground and got the better of Cox.

Jim Washburn immediately turned his attention to the next defensive lineman up. But Cullen Jenkins, an eight-year veteran, decided it was time to give the rookie some pointers, taking him aside and offering up some instruction.

On the first day of hitting, the Eagles suffered their first significant injury of the year.

Wide receiver Riley Cooper sustained a left collarbone fracture Saturday and exited practice to undergo X-rays. The injury happened on a one-on-one against cornerback Curtis Marsh. Both players went up for the ball, and Cooper ended up on the ground and began pounding his fist on the turf.

Cooper is thought to be the fourth receiver behind DeSean Jackson, Jeremy Maclin and Jason Avant, but this certainly clouds the picture.

We’ve been so consumed with other questions about Brandon Graham  (Can he get past the knee injury? Was he a mistake? Can he make a comeback?) that we have forgotten to ask something very important.

Is he a fit for this system?

He was drafted before Jim Washburn got here, after all. Some men are Wide-9 guys, and some aren’t. What category does Graham fall into? Depends who you ask.

Eagles quarterbacks past and present spent some quality time together recently as Ron Jaworski sat down for a two-hour interview with Michael Vick at NFL Films. Here are some highlights.

Each morning during training camp, we’ll be bringing you the Eagles wake-up call with links and notes from Lehigh. In this installment, find out how Vegas feels about the Birds, and discover which wide receiver the Eagles recently tried to add.

There were no defenders on the field, and the Eagles were not wearing pads. But let the record show that on July 27, 2012, at around 3:21 p.m., Michael Vick slid.

And then he celebrated.

As Vick was running, someone in the crowd yelled for the Eagles’ quarterback to slide. Whether he heard the person or not, I don’t know. But Vick got down on the ground, popped back up and tossed the football up in the air as the crowd went wild. He then ran back to his teammates, shared a laugh with Jason Kelce, and that was that.

Baby steps, my friends. Baby steps.

These long afternoon practices in the burning Lehigh sun are going to take some getting used to. Just ask DeSean Jackson.

During 7-on-7 drills, Jackson took off on a fly pattern down the left sideline, locked in a battle with Nnamdi Asomugha. Michael Vick overthrew Jackson, who returned to the pack out of gas. He lost his lunch, then spent the next few minutes on bended knee with a cold towel over his head.

Later in the practice, the scene repeated itself.

Keeping you up-to date on the latest with the ‘backers. Today, DeMeco Ryans immediately asserts his authority, and Brian Rolle is the man to beat both at the WILL and in the nickel.

It’s tough to tell whether Jaiquawn Jarrett feels any sense of urgency this summer.

After this morning’s practice, I stopped the Eagles’ second-year safety and asked him a few questions about what he hopes to prove in the next few weeks, and whether he thinks he’ll compete for a starting spot.

“It’s all about competing. That’s what I’m here to do,” Jarrett said. “I’m going to compete for the starting spot. Each safety here’s going to compete for the starting spot. We’re all going to push each other and make each other better.”

The Eagles don’t plan on using DeSean Jackson as their primary punt returner this year.

“I want him to concentrate on the receiving end of it,” Reid said. “And most of all, we think we have guys that can contribute there and be effective, and that are explosive players. Now we have to see.”

For now, two of those guys are fourth-round pick Brandon Boykin and undrafted free agent Damaris Johnson.

The tight end position is quickly becoming a regular topic of conversation up at Lehigh. Having already explored a couple free agent options, the Eagles have made it known that at the very least, they wouldn’t mind bringing in some competition for the like of Clay Harbor. And now their primary option, Brent Celek, is banged up.

An MRI revealed a slight sprain of the MCL in his right knee. Celek is coming off hip surgery, and the latest injury happened just a few snaps into his first practice of the season. Is it time to bring someone in?

Clay Harbor was out of breath.

The Eagles tight end was one of the last players off the practice field Thursday afternoon. As he walked toward the locker room, Harbor was met by reporters and knew the questions that were coming his way.

The Eagles have shown interest in Visanthe Shiancoe and Jeremy Shockey this week. The implication is pretty clear: Find someone to push Harbor for the No. 2 tight-end spot behind Brent Celek.

“If anything, it just motivates you more,” Harbor said, doing his best to say the right things. “I mean, competition is competition. You get competition in the National Football League all the time.”
