Jackson was listed as limited Wednesday due to a back injury, Mike Garafolo of NFL Network reports.
According to Jeff Zrebiec of The Athletic, Jackson wasn't on the field early in Wednesday's practice but later joined his teammates. Coach Jesse Minter downplayed the issue after practice, and now it's official that Jackson is dealing with a back issue. Jackson's status for Sunday doesn't appear to be in jeopardy at this stage, but this will be one to monitor going into the weekend.
