Herbert is expected to play in Thursday's preseason finale against the Rams, Alex Insdorf of BoltBeat.com reports.
The Chargers plan to get their key personnel one more dose of game action before the season gets underway. Other than Derwin James and Khalil Mack, the starters will be on the field for about 6-8 plays. After that final tuneup, Herbert and the Chargers will get ready for Week 1 against the Cardinals.
