Eagles coach Andy Reid said Friday he wouldn't know until game time whether or not they will play.
Wide receiver Riley Cooper was scratched by the Eagles because of a broken collarbone, leaving the Eagles with only three healthy receivers. Cornerback Curtis Marsh is questionable with a hamstring injury and will be another game-time decision.
Jackson injured his hamstring during Wednesday's practice. Maclin, who returned after a hip injury in Sunday's season-opening win against the Cleveland Browns, has not practiced the past two days.
