The Browns placed Njoku (knee) on injured reserve Monday.
Njoku will miss at least three weeks on IR after suffering a knee injury during Sunday's loss to the Ravens. As long as he remains sidelined, Harrison Bryant and Stephen Carlson stand to see increased opportunities behind Austin Hooper. Njoku got off to a promising start Week 1 before suffering his knee injury, hauling in all three of his targets for 50 yards and a score.
