The likelihood of Reggie Brown playing in Sunday's season opener against the St. Louis Rams decreased this afternoon when the veteran wide receiver was unable to participate in practice.

Brown, who is recovering from a strained left hamstring he suffered in the second preseason game against Carolina, had taken part in individual drills during Wednesday's practice, but obviously is not fully recovered from his injury.

Earlier in the day, offensive coordinator Marty Mornhinweg had hinted that Brown might not be ready.

"We don't know," Mornhinweg said. "Reggie is day to day right now, so DeSean (Jackson) will start at the front flanker it looks like."

Even if Brown is OK, Jackson is going to start at the "Z" wide receiver position. He'll be the first Eagles rookie to start at wide receiver since Calvin Williams in 1990. If Brown is able to start, he'd be at the "X" wide receiver position. If Brown can't play, the snaps will be divided among Hank Baskett, Greg Lewis and Jason Avant.
