This opens a three-week window of time for the Browns to activate Njoku from injured reserve and add him to their 53-man roster.
Njoku requested a trade of Cleveland this summer before changing his mind.
Njoku, 24, is a former first-round pick of the Browns back in 2017. He’s entering the fourth year of his four-year, $9.5 contract and stands to make a base salary of $1.76 million for the 2020 season.
The Browns picked up Njoku’s fifth-year option back in April that will cost them roughly $6 million for the 2021 season.
In 2020, Njoku has appeared in one game for the Browns and caught three passes for 50 yards receiving and one touchdown.
