Jackson (back) is participating at Friday's practice, Jeff Zrebiec of The Athletic reports.
Jackson sat out practice the past two days while managing back soreness, so it's a good sign to see him back on the field, even if he only ends up working as a limited participant. It's unclear whether the 24-year-old will end up with an injury designation for Sunday's matchup with the Broncos, though he at least appears to be trending in the right direction.
