Glazer's also reporting that Jackson had some memory loss after the hit.
The Eagles play the Titans in Week 7 and then have a bye so it seems very likely that Jackson would sit next weekend and then get a couple of weeks off. At this point, the best case scenario likely has him returning in Week 9.
This is the second confirmed concussion of Jackson's career.
