Kmet is under evaluation for a possible concussion during Sunday's contest at Cincinnati.
Kmet visited the medical tent in the second quarter and then walked to the locker room before the Bears made this announcement. At the time of his departure, he'd hauled in one of two targets for 10 yards and also was 0-for-1 passing. Rookie first-rounder Colston Loveland is poised for more work for as long as Kmet is sidelined.
