Four defensive backs pepper the Friday injury report released by the Chiefs for their Week 7 game against San Diego. Included are safety Eric Berry (ankle) and cornerback Chris Owens (knee), who have been ruled out. Sean Smith (groin) is questionable while fellow cornerback Phillip Gaines (concussion) is probable.
The two exceptions are wide receiver Donnie Avery (groin), who is out, and running back Cyrus Gray (hand), who is questionable.
