Gilchrist hurt his elbow, though it was unclear what happened to Fluker. Backup safety Jahleel Addae also went to the locker room briefly, but returned to the field.
The banged-up Chargers were already playing without wide receiver Keenan Allen (shoulder) and running back Ryan Mathews (ankle). Trevor Robinson also started in place of the injured Chris Watt, becoming the fifth center to start a game this season.
