Jackson was coming off a sub-par game with 63 yards and no scores in Week 8 against the Giants, but it had little to do with an ankle sprain. He did catch eight balls, though, so it's a little strange that he couldn't put up more yards.
Jackson was very quiet in Week 7 with only three catches and 21 yards against the Cowboys, so he's coming in kind of cold. Still, there's nothing wrong with him and the Eagles don't have many reliable options outside of Jackson.
Fantasy impact: There's nothing to worry about with Jackson and he has a chance to bust loose for a couple of long plays on Sunday. Nick Foles is going to start at quarterback and Jackson actually has put up some solid numbers with him. There aren't many better options than Jackson and he's a must-start option this week.
