Hubbard (ankle) was forced to take a cart off of the practice field Sunday, Paul Dehner Jr. of The Athletic reports.
Hubbard has been working his way back from offseason ankle surgery, and it's unclear if Sunday's issue was a result of the recovering ankle or something separate. The defensive lineman initially walked off the field with a trainer, but he ultimately hopped on a cart to take him back to the locker room during the team's 11-on-11 session. The Bengals will reconvene for practice Monday, and more information on his status will likely be provided then.
