Kroft (foot) has been ruled out for Sunday's game against the Steelers, Katherine Terrell of ESPN.com reports.
The news comes as no surprise, as Kroft was seen sporting a walking boot Wednesday and getting around the Bengals' locker room on a scooter. With Kroft out and Tyler Eifert (ankle) on IR, C.J. Uzomah will head the team's tight end corps Week 6 and possibly beyond if Kroft's injury lingers.
