Njoku (ankle) was part of a group of players that worked off to the side with trainers during Wednesday's practice session, Chris Easterling of the Akron Beacon Journal reports.
Njoku missed the Browns' previous game before the team's bye, and his status remains uncertain heading into Sunday's contest in Miami. While the tight end and Jeremiah Owusu-Koramoah (knee) worked out on the side Wednesday, both were officially listed as non-participants on Cleveland's injury report, with Easterling noting that head coach Kevin Stefanski remains non-committal about either player's Week 10 status.
