Jackson leads the team with 45 catches and 700 yards receiving, but has only two touchdowns. Coach Andy Reid says the injury could take six weeks to heal.
Reid says running back LeSean McCoy remains in phase one of his concussion recovery and Michael Vick is in the fourth of five stages. Vick has missed the last two games and McCoy didn't play against the Panthers.
The Eagles (3-8) have lost seven straight games. They'll visit Dallas (5-6) next Sunday night.
