PHILADELPHIA (973espn.com) - The Eagles didn't add anything at the trade deadline but could be getting a far more impactful boost Sunday when the Chicago Bears visit Lincoln Financial Field.

Receiver DeSean Jackson is creeping closer to a return from a core-muscle injury that has left the 32-year-old deep threat sidelined since tapping out of the Week 2 game in Atlanta very early.

“Desean’s been looking really good,” Eagles coach Doug Pederson Wednesday morning before practice began at the NovaCare Complex. “He’s been working hard through his rehab. I expect to get him into practice a little bit today and see where he's at physically. I’m optimistic, obviously, and we’ll take it day by day.”

Jackson opted for rehab over surgery for his issue and has again flown in his personal trainer this week in an attempt to get ready for Sunday against the Bears, according to a league source.

From Jackon's perspective, the goal is to get to the point where he is himself from a speed standpoint but the veteran understands he will be playing through some pain and discomfort for the rest of the season, something Pederson admitted previously.

Jackson's return to the practice field will be on a limited basis and the fact that the Eagles' bye week comes after the Chicago game could also affect any decision-making.

In Jackson’s absence, Philadelphia has struggled mightily at receiver with Nelson Agholor, Mack Hollins and rookie J.J. Arcega-Whiteside being unproductive for the most part. Jackson, on the other hand, piled up 154 receiving yards and two long touchdowns in the season-opening win over Washington.
