Njoku was held out of Wednesday's practice, with the Browns designating his injury as "knee/rest", Jake Trotter of ESPN.com reports.
The addition of "rest" rather than just the "knee" label alone comes as a comfort to fantasy managers who intend to use Njoku in lineups for his Week 5 matchup with the Chargers -- a team he roasted for a career-high 149 receiving yards last season. It was one of his few productive receiving outings of 2021, but Njoku now is averaging 4.5 catches for 50.3 yards per game in a three-down role through the first four weeks of 2022. He'll likely return to practice later this week and suit up Sunday.
