Eagles vs. Bengals

— Another scare, another guarantee from an otherwise preoccupied Jeremy Maclin.

Maclin went down during Monday's practice at training camp, apparently with a leg injury. He returned to drills a little while later but then pulled himself out again for good.

When he left the field after practice, visibly annoyed at the crowd and questions he knew he would draw, the wide receiver did not stop to address the issue but did say he was "OK" and that he would be back "out there tomorrow."

Of course that doesn't necessarily mean he'll be practicing. He could be like a handful of others who were just off to the side watching with various injuries, like center Julian Vandervelde (back), running back Chris Polk (hamstring), wide receivers Jeff Maehl (foot) and Riley Cooper (ankle), linebacker Jake Knott (hamstring) and cornerback Nolan Carroll (unspecified).

For what it was worth, Maclin was not limping or walking gingerly as he left the field.

This was the second time something like this has happened with him since he got back on the field following a 2013 season spent on the injured reserve list while recovering from surgery to repair a torn ACL.

During OTAs, he collapsed at the end of a practice but proclaimed himself OK then too.

Greene making an impact

Former star linebacker Kevin Greene is in town for three days to help the Eagles get to the quarterback with the same frequency as he did: 160 times over his 15-year career.

Greene, 52, walked away from his job as a Green Bay Packers assistant coach at the end of last season to spend more time with his family and has said he would like to return to coaching once his children are out of the house. But for now, it's just a few appearances here and there.

He has worked with all the outside linebackers, attempting to refine or add to their technique.

"In college … I didn't really look into him until I started playing defense," rookie linebacker Marcus Smith said. "We would be watching film, our coaches used to talk about him. So it's just an honor to be out here with him so he can coach me up on some things that I might be doing wrong."

Play of the day

Stock rising

OLB Travis Long. The way he's played this summer, he's got more than a puncher's chance to not only make the team but make an impact.

Stock falling

CB Roc Carmichael. Solid special teams player but the numbers are working against him because of the additions of Nolan Carroll and draft pick Jaylen Watkins. Hasn't done a lot in this camp to make himself stand out — at least in terms of play on the field.

In the spotlight

OT Jason Peters. Not really talked about until the Hall of Fame ceremonies this past weekend, when it was pointed out by many that he's really the only active Eagle who could be considered worthy of induction if his career ended tomorrow. He just keeps plugging along, bullying (in a good way) everyone who tries to cross his path.

Merrill Reese says …

"You never know if they're going to break records [as they did for points and yardage a year ago] but [the Eagles] are going to be an explosive offensive team, no question. They have to be explosive."
