Njoku is listed as a limited participant on Wednesday's estimated practice report due to a knee issue, Nate Ulrich of the Akron Beacon Journal reports.
The seemingly minor knee injury is likely less relevant than Austin Hooper's return Wednesday from the reserve/COVID-19 list. Njoku played every snap on offense in Monday's 16-14 loss to the Raiders, but he'll likely be back in a part-time role this Saturday in Green Bay.
