The team announced on Monday that they had placed the franchise tag on David Njoku.
The deadline for teams to designate players is Tuesday. Time.
If the two parties don't agree on a long-term contract by July 15, he will play the 2022 season on the franchise tender.
In five seasons with the Browns, Njoku has totaled 148 catches, including 36 for 475 yards and four touchdown last season.
His best season was in Baker Mayfield's first year as a starter, when he hauled in a career-best 56 catches for 639 yards. Over the past three seasons, Njoku's production has decreased rapidly.
In the summer of 2020, Njoku requested a trade from Cleveland. He withdrew the request after the beginning of training camp.
After the team exercised his fifth-year option, Njoku was paid $6.01 million last season.
