Dickinson aggravated his previous shoulder injury in Thursday's game against the Jets, Ben Pope of the Chicago Sun-Times reports.
Dickinson has been dealing with this injury for a few weeks, and it cropped up again during Thursday's contest. The 30-year-old's status is questionable for Saturday versus the Oilers. If Dickinson is forced out of the lineup for a stretch, the Blackhawks could opt to put him on injured reserve to free up a roster spot.
