Njoku has been ruled out for the remainder of Monday's game against the Jets with a concussion, Nate Ulrich of the Akron Beacon Journal reports.
Demetrius Harris, Pharaoh Brown and Ricky Seals-Jones are slated to fill in for Njoku at tight end. The former first-round pick will need to clear the concussion protocol in order to play against the Rams in Week 3.
