Jackson (shoulder) didn't take part in Wednesday's practice, Chris Russell of ESPN 980 Washington reports. Jackson emerged from Week 2 with a mild sprain of the AC joint in his left shoulder, so his absence isn't much of a surprise. Nevertheless, owners should keep a close eye on his status as the week goes on, despite his contention that he doesn't "plan on missing" his return to Philadelphia on Sunday, according to Mike Jones of the Washington Post.
