About that offensive line ...

With reporting from Bob Cooney at Lehigh ...

The Eagles spent $100 million on upgrades to the offensive line, but even Andy Reid conceded this morning that it is hard to know what they have until the group plays together at some point.

The Birds took another small step AWAY from that likelihood as left guard Todd Herremans missed the morning session with a swollen ankle. Heremans seemed to be limping as he left the locker room and is unlikely to practice in today's afternoon session, a 10-10-10 practice in shorts. Reid said he did not think "it was too much of a big deal there."

That leaves center Jamaal Jackson as the only one who has made it through every practice thus far at Lehigh.

On the positive side, left tackle Jason Peters took part in his first full contact practice after suffering a quad strain at the start of camp. Reid would not commit to whether Peters or Stacy Andrews, recovering from offseason ACL surgery, would play in Thursday's preseason opener against New England.

Where Shawn Andrews' condition is remains the thorniest issue. Andrews, who missed all but the first two games of last season with a back injury, has still not been on the field. Reid seemed somewhat annoyed with the lack of progress during his morning news conference and did not rule out the possibility that Andrews could miss the season opener.

“I don’t know that. I can’t tell you that," Reid said of Andrews' playing in the opener. "I just know that he’s getting better. But, until he’s out here I can’t predict that.”

In other injury news, wide receiver DeSean Jackson missed the morning practice but was outdoors doing some rehab work on the side. Jackson hyperextended his knee Saturday. Reid said he would have practiced had the field conditions been a little better. The rain did not stop until about 10 minutes before practice.

Cornelius Ingram left the facility after practice with head athletic trainer Rick Burkholder. Ingram will have surgery to repair the torn ACL he suffered last Tuesday, although Reid said he did not know when.

Also, tight end Matt Schobel remained sidelined with a calf injury, leaving the tight ends as starter Brent Celek and rookies Eugene Bright and Rob Myers.

Reid also said he now knew more about the incident that led to Juqua Parker's arrest for marijuana possession. Herremans was cited for two minor traffic violations at the time.

"I’ve got to let the law take care of that side of it," Reid said. "And then, we can proceed from there. I’m not going to disclose the discipline or any of that, I’d never do that.”
