"Electric receiver and returner DeSean Jackson didn't play after the beginning of the fourth quarter.

As the rest of the Eagles tried desperately to come back against the Saints, Jackson, the team's most dynamic player, limited his action to the sideline. His angry groin, flaring all week, finally cost him playing time.

Any time the Eagles are without Jackson, it matters.

He returned a punt for a touchdown in the season opener. He caught a 71-yard bomb to tie the score in today's home opener. With Michael Vick suspended the first two games, Jackson has been the main cog in the Birds' Wildcat offense.

And, with just four receivers active today, he was absent with the team in comeback mode.

Eagles coach Andy Reid said of Jackson's injury, "I think we'll be fine there."

Jackson, meanwhile, was less certain."
