Brown (concussion) is not practicing Tuesday, the San Diego Union-Tribune reports.

Analysis:

Brown missed last weekend's game due to a concussion and since he still hasn't been cleared to practice, he seems doubtful to be ready for Thursday's game versus Denver. As a result, Branden Oliver will likely maintain his role as the Chargers' top running back.
