The franchise tag means Njoku will be under contract through the 2022 season for roughly $11 million. The team is expected to continue negotiating a long-term deal with him.
Following the season, Njoku said his heart was in Cleveland.
“I love it here. I love it here to the core,” he said. “I honestly want to be here for the rest of my career, so my agent and the Browns are still in talks, we’re still negotiating, figuring out what we can do, and we’ll go from there.”
Njoku has 148 career receptions for 1,754 yards and 15 TDs in five seasons with the Browns. His 71-yard touchdown catch against the Los Angeles Chargers last season was the longest in the NFL by a tight end.
Cleveland also tendered contracts to exclusive rights free agent wide receiver Ja’Marcus Bradley and offensive linemen Blake Hance and Michael Dunn.
Bradley had four catches for 64 yards in five games last season.
Hance started six games at right tackle and two at left tackle last year when Jack Conklin and Jedrick Wills Jr. were injured.
Dunn started two games at right guard in 2021.
