Adeniji hurt his right knee in Saturday's preseason loss to Green Bay and exited the stadium on crutches, Zac Jackson of The Athletic reports.
Adeniji was hurt on a pass play that resulted in a Tyler Huntley interception early in the third quarter. It was a rough day for Cleveland's offensive line, as fellow tackles James Hudson (ankle) and Germain Ifedi (hand) also departed with injuries. Adeniji has been competing for a depth role in the preseason, and his chance of making the 53-man roster could take a hit if he's unable to play in the Browns' final exhibition game next Saturday against Seattle.
