Njoku (ankle) has been ruled out for Sunday's game against the Dolphins, Jake Trotter of ESPN.com reports.
With Njoku -- who last suited Week 7 -- still sidelined, Harrison Bryant is in line to lead the Browns' tight end corps Sunday. Meanwhile, Pharaoh Brown should serve as Bryant's main backup, and Miller Forristall is a candidate to be elevated from the practice squad to add further depth to the position group. Njoku's next chance to play will arrive Week 11, when Cleveland faces Buffalo on the road.
