Njoku had the cast removed from his broken wrist, suffered in a Week 2 win over the Jets, George M. Thomas and Marla Ridenour of the Akron Beacon Journal report.
Njoku, who is on injured reserve, is optimistic he'll be back this season. The earliest he can return is Week 12, a Nov. 24 game against the Dolphins. With injuries mounting for the Browns at tight end -- Pharaoh Brown is in the concussion protocol and Ricky Seals-Jones left Sunday's contest with a knee injury -- designating Njoku as one of the team's IR returnees seems likely.
