PHILADELPHIA (AP) Brian Westbrook remains sidelined with a concussion and DeSean Jackson's status for Philadelphia's game at Atlanta is uncertain after he sustained a head injury.

Westbrook will miss his third straight game after sustaining his second concussion in a three-week span on Nov. 15. The former All-Pro running back saw concussion specialists this week in Pittsburgh and will be re-examined in a week or two. Westbrook is expected to increase his exercise regimen. He experienced a headache working out last Friday.

Jackson, the Eagles' big-play wide receiver, was injured in a win over Washington last Sunday. Coach Andy Reid says Jackson is "making progress" recovering from his concussion and wouldn't rule him out for Sunday's game against the Falcons.
