Jackson left the game after he was hit on a catch late in the third quarter. The Eagles originally said Jackson suffered head and neck injuries.
Jackson has developed into Philadelphia's No. 1 wide receiver this season with 44 catches for 769 yards and six touchdowns. He finished with two receptions for 41 yards in Philadelphia's 27-24 win on Sunday, including a 35-yard touchdown.
The Eagles played without running back Brian Westbrook after he suffered a concussion Oct. 26 at Washington.
