Eagles wide receiver DeSean Jackson hasn't made much progress since suffering a concussion in Week 6 against the Falcons. Jackson won't face the Titans on Sunday and is still sore in his neck and shoulder areas. "Really, it's more the place where DeSean took the hit that's more sore than the head," Reid said. "His mind's clear -- he hasn't passed the test yet but his mind's clear. He feels good in that area, but just the area on the right side where [Robinson] hit him there, so it's a bit sore. "And then kind of up through his back and neck area, just from the shock of the hit there." Jackson hasn't passed the first of several concussion exams he must clear before he can practice.
